Abstract

A fixing device includes a rotating unit, a heating unit configured to heat the rotating unit, and a pressure member configured to nip a recording material between the rotating unit and the pressure member and to convey the recording material. In addition, a control portion is configured to variably control, when the rotating unit is changed from a rotating state to a halt state, a heating temperature of the heating unit in the halt state according to the heating temperature of the heating unit in the rotating state.

Claims (22)

1. A fixing device, comprising:

a rotating unit;

a heating unit configured to heat the rotating unit;

a pressure member configured to nip a recording material between the rotating unit and the pressure member and to convey the recording material; and

a control portion configured to variably control, when the rotating unit is changed from a rotating state to a halt state, a heating temperature of the heating unit in the halt state according to the heating temperature of the heating unit in the rotating state.

2. The fixing device according to claim 1 ,

wherein the control portion sets the heating temperature in the rotating state according to information of a basis weight of the recording material.

3. A fixing device comprising:

a rotating unit;

a heating unit configured to heat the rotating unit;

a pressure member configured to nip a recording material between the rotating unit and the pressure member and to convey the recording material; and

a control portion configured to control, when the rotating unit is changed from a rotating state to a halt state, whether or not a heating operation of the heating unit is to be performed in the halt state according to a heating temperature of the heating unit in the rotating state.

4. The fixing device according to claim 3 ,

wherein the control portion sets the heating temperature in the rotating state according to information of a basis weight of the recording material.

5. A fixing device comprising:

a rotating unit;

a heating unit configured to heat the rotating unit;

a pressure member configured to nip a recording material between the rotating unit and the pressure member and to convey the recording material; and

a setting portion configured to set a heating temperature of the heating unit when the rotating unit is changed from a rotating state to a halt state,

wherein, when a heating temperature of the heating unit in the rotating state is a first temperature, the setting portion sets the heating temperature of the heating unit in the halt state to a second temperature, and, when a heating temperature of the heating unit in the rotating state is a third temperature that is less than the first temperature, the setting portion sets a heating temperature of the heating unit in the halt state to a fourth temperature that is less than the second temperature.

6. The fixing device according to claim 1 ,

wherein the rotating unit is a cylindrical film.
