摘要： An image forming apparatus includes a driving source, a supply roller which supplies a recording sheet, a fixing device, a fixing driving gear mechanism which transmits a driving force of the driving source to the fixing device, a supply driving gear mechanism which transmits the driving force to the supply roller, and a control device. The control device controls the driving source to rotate in one direction when a temperature of the fixing device exceeds a predetermined temperature, and to rotate in a reverse direction when the temperature is the predetermined temperature or lower. The fixing driving gear mechanism includes a mechanism which interrupts a transmission of the driving force when rotating in the reverse direction. The supply driving gear mechanism includes a mechanism which causes a rotating direction of the supply roller to be the same when the driving source rotates in both directions.

摘要： An image forming apparatus includes gears for driving a first photosensitive drum and a second photosensitive drum. The gears includes a first drum gear, a second drum gear, and a first drive gear configured to apply a rotational force to the first drum gear and the second drum gear by meshing with the first drum gear and the second drum gear. Specific positional relations among the first photosensitive drum, the second photosensitive drum, the first drum gear, the second drum gear, and the first drive gear are configured based on exposure positions and transfer position. Such an image forming apparatus may reduce an occurrence of an image formation failure even when the dimensional unevenness of the gears occurs.
