Abstract
A image forming apparatus includes an electrostatic latent image carrier that carries an electrostatic latent image, a developer supplying unit that supplies a developer to the electrostatic latent image and forms a developer image, a transfer roller that transfers the developer image to a recording medium, a heating roller with a heater therein, a temperature sensor that detects the temperature of the heating roller, a heating roller driving mechanism that drives the heating roller, and a controller that cools down the heating roller if the controller determines that the temperature sensor detects a temperature equal to or higher than a first temperature within a threshold time after completion of image forming.
Claims12
A image forming apparatus comprising:
- an electrostatic latent image carrier that carries an electrostatic latent image;
- a developer supplying unit that supplies a developer to the electrostatic latent image and forms a developer image;
- a transfer roller that transfers the developer image to a recording medium;
- a heating roller with a heater therein;
- a temperature sensor that detects a temperature of the heating roller;
- a heating roller driving mechanism that drives the heating roller;
- and
- a controller that cools down the heating roller if the controller determines that the temperature sensor detects a temperature equal to or higher than a first temperature within a threshold time after completion of image forming.
An image forming method comprising:
- forming an image;
- counting time from if the image is completely formed;
- and
- cooling down a heating roller if the controller determines that a temperature sensor detects a temperature equal to or higher than a first temperature within a threshold time after completion of image forming.
