Abstract

A support member for a heater includes a main body extending longitudinally between a pair of end portions and a pair of first contact portions. Each first contact portion is coupled to one of the end portions of the main body. A gap is formed between each first contact portion and the main body. The support member is configured such that, when the heater is coupled to the support member (a) the gaps each receive the heater, (b) the first contact portions each engage a first surface side of the heater, and (c) the main body engages a second surface side of the heater opposite the first surface side.

Claims (36)

1 . A support member for a fixing device heater, the support member comprising:

a main body extending longitudinally between a pair of end portions, the main body having an inclined surface relative to a longitudinal direction of the main body; and

a pair of first contact portions, each first contact portion being coupled to one of the end portions of the main body, a gap being formed between each first contact portion and the main body;

the support member being configured such that, when the fixing device heater is coupled to the support member:

the inclined surface receives an end of the fixing device heater and guides the end of the fixing device heater into one of the gaps;

the gaps each receive the fixing device heater;

the first contact portions each engage a first surface side of the fixing device heater; and

the main body engages a second surface side of the fixing device heater opposite the first surface side.

2 . The support member of claim 1 , further comprising a pair of second contact portions, each second contact portion being coupled to one of the first contact portions, wherein the support member is configured such that, when the fixing device heater is coupled to the support member, the second contact portions limit longitudinal movement of the fixing device heater relative to the support member.

3 . The support member of claim 2 , further comprising a pair of third contact portions coupled to one of the first contact portions, wherein the support member is configured such that, when the fixing device heater is coupled to the support member, the third contact portions limit lateral movement of the fixing device heater relative to the support member.

4 . The support member of claim 3 , wherein the main body, the first contact portions, the second contact portions, and the third contact portions are formed as a single, continuous piece.

5 . The support member of claim 1 , wherein the first contact portions are longitudinally spaced from one another such that, when the fixing device heater is coupled to the support member, a portion of the first surface side of the fixing device heater is exposed.

6 . The support member of claim 5 , wherein the main body includes a support portion having a rounded surface that extends away from the fixing device heater when the fixing device heater is coupled to the support member.

7 . The support member of claim 1 , wherein the main body at least partially defines an opening positioned to expose an electrical contact of the fixing device heater.

8 . The support member of claim 7 , further comprising a second contact portion coupled to one of the first contact portions and partially defining the opening, wherein the support member is configured such that, when the fixing device heater is coupled to the support member, the second contact portion limits longitudinal movement of the fixing device heater relative to the support member.

9 . A support member for a fixing device heater, the support member comprising:

a first contact portion positioned to contact a first surface side of the fixing device heater; and

a support portion main body extending in a longitudinal direction and coupled to the first contact portion, the support portion main body being positioned to contact a second surface side of the fixing device heater that is opposite the first surface side of the fixing device heater, the support portion main body having an inclined surface relative to a longitudinal direction of the support portion main body,

wherein a gap is defined between the support portion main body and the first contact portion, the gap being sized to receive the fixing device heater, and the gap extending longitudinally to permit the fixing device heater to move in the longitudinal direction with respect to the support portion main body, and

wherein the inclined surface receives an end of the fixing device heater and guides the end of the fixing device heater into one of the gaps.

10 . The support member of claim 9 , wherein the support member is configured to bend to facilitate coupling the fixing device heater to the support member.

11 . The support member of claim 10 , wherein:

an orthogonal direction is defined perpendicular to a lateral direction and the longitudinal direction; and

the support member is configured to bend such that a longitudinal end portion of the support member deflects in the orthogonal direction to facilitate coupling the fixing device heater to the support member.

12 . The support member of claim 9 , wherein the support portion main body at least partially defines an opening positioned to expose an electrical contact of the fixing device heater.

13 . The support member of claim 12 , further comprising a second contact portion coupled to the first contact portion and positioned such that the opening extends between the support portion main body and the second contact portion, the second contact portion being positioned to contact a longitudinal end portion of the fixing device heater.

14 . The support member of claim 9 , further comprising a second contact portion coupled to the first contact portion and positioned to engage a longitudinal end portion of the fixing device heater to limit longitudinal movement of the fixing device heater.

15 . The support member of claim 14 , wherein the support portion main body, the first contact portion, and the second contact portion are formed as a single, continuous piece.

16 . The support member of claim 14 , further comprising a pair of third contact portions each coupled to the first contact portion and positioned to engage the fixing device heater to limit lateral movement of the fixing device heater.

17 . A support member for a fixing device heater, the support member comprising:

a main body extending in a longitudinal direction between a first end portion and a second end portion, the main body having a first contact surface facing in a first orthogonal direction that extends perpendicular to the longitudinal direction and a lateral direction, the main body having an inclined surface relative to the longitudinal direction; and

a first contact portion coupled to the first end portion of the main body, the first contact portion having a second contact surface facing in a second orthogonal direction opposite the first orthogonal direction, a gap being formed between the first end portion and the first contact portion,

wherein the inclined surface receives an end of the fixing device heater and guides the end of the fixing device heater into one of the gaps.

18 . The support member of claim 17 , further comprising a second contact portion coupled to the first contact portion and extending beyond the second contact surface in the second orthogonal direction.

19 . The support member of claim 18 , further comprising a pair of third contact portions coupled to the first contact portion and laterally offset from one another.

20 . The support member of claim 17 , further comprising a second contact portion coupled to the second end portion of the main body, the second contact portion having a third contact surface facing in the second orthogonal direction, a second gap being formed between the second end portion and the second contact portion.
