ELECTRONIC APPARATUS THAT ANNOUNCES NECESSITY TO PREPARE FOR RESTORATION OF DRIVE ROLLER, BEFORE RESTRICTING ROTATION THEREOF, AND IMAGE FORMING APPARATUS

An electronic apparatus includes a drive roller, a contamination detection device that detects a degree of uncontaminatedness of a surface of the drive roller, a drive motor, a controller, and a display device. The controller executes a first feedback control, when the degree of uncontaminatedness i...

Zusammenfassung:	An electronic apparatus includes a drive roller, a contamination detection device that detects a degree of uncontaminatedness of a surface of the drive roller, a drive motor, a controller, and a display device. The controller executes a first feedback control, when the degree of uncontaminatedness is equal to or higher than a first threshold, executes a second feedback control including increasing the driving force to the drive motor, and displays a first screen announcing necessity to prepare for restoration of the drive roller on the display device, when the degree of uncontaminatedness is lower than the first threshold, and equal to or higher than a second threshold lower than the first threshold, and restricts the drive roller from rotating, and displays a second screen requesting restoration of the drive roller on the display device, when the degree of uncontaminatedness is lower than the second threshold.
