4. The connector member according to claim 1 , wherein the energizing terminal is a bent plate structure.
5. The connector member according to claim 1 , wherein the energizing terminal has a plurality of bent portions between the connecting portion and the contact portion.
6. The connector member according to claim 1 , wherein the energizing terminal has a reinforcing portion on the second side of the recess.
7. The connector member according to claim 6 , wherein the energizing terminal further includes:
a back surface portion extending along the second direction and connected to the connecting portion, and
a pair of side surface portions each connected to an end of the back surface portion in the second direction and extending in the third direction.
8. The connector member according to claim 7 , wherein the connecting portion is at an end portion of the back surface portion in the second direction.
9. The connector member according to claim 1 , wherein the conducting wire is connected to the connecting portion in the second direction.
10. The connector member according to claim 1 , wherein the conducting wire is connected to the connecting portion in the third direction.
11. A fixing device, comprising:
a heating roller including a heating unit and configured to rotate about a rotation axis extending in a first direction; and
a connector member connected to the heating unit and including:
a cover having a recess into which an end part of the heating unit in the first direction is inserted in a second direction crossing the first direction, and
an energizing terminal stored in the cover and including:
a contact portion on a first side of the energizing terminal in a third direction to contact a contact point on the end part in the recess, and
a connecting portion on a second side of the energizing terminal opposite to the first side in the third direction across the end part in the recess, the connecting portion being connected to a conducting wire for receiving electric power, wherein
the energizing terminal contacts the end part in the recess only on the first side thereof and does not contact any member in the recess on the second side thereof.
12. The fixing device according to claim 11 , further comprising:
a pressure roller that contacts the heating roller from the first side of the recess.
13. The fixing device according to claim 11 , wherein an end portion of the conducting wire connected to the connecting portion is a straight line portion.
14. The fixing device according to claim 11 , wherein the energizing terminal is a bent plate structure.
15. The fixing device according to claim 11 , wherein the energizing terminal has a plurality of bent portions between the connecting portion and the contact portion.
16. The fixing device according to claim 11 , wherein the energizing terminal has a reinforcing portion on the second side of the recess.
17. The fixing device according to claim 16 , wherein the energizing terminal further includes:
a back surface portion extending along the second direction and connected to the connecting portion, and
a pair of side surface portions each connected to an end of the back surface portion in the second direction and extending in the third direction.
18. The fixing device according to claim 17 , wherein the connecting portion is at an end portion of the back surface portion in the second direction.
19. The fixing device according to claim 11 , wherein
the end part of the heating unit in the recess includes a first outer surface exposed to the first side of the energizing terminal and including the contact point and a second outer surface exposed to the second side of the energizing terminal, and
the second outer surface of the end part is not in contact with any part of the energizing terminal.
20. The fixing device according to claim 11 , wherein
the end part of the heating unit in the recess includes a substrate facing the first side of the energizing terminal and a supporting member facing the second side of the energizing terminal, and
the energizing terminal on the second side is not in contact with the supporting member.
