ABSTRACT:
An image forming apparatus has a chassis, a feed roller rotatably supported by the chassis, a feed roller gear relatively unrotatably coupled to the feed roller, a motor that drives the feed roller, a drive gear that receives driving force from the motor, and an intermediate gear having a gear portion that engages the drive gear and the feed roller gear and an axle portion that is rotatably supported to the chassis via intermediate gear bearings. At least one of the intermediate gear bearings includes a substantially circular inner surface and a stepped portion that is depressed from the circular inner surface. The axle portion of the intermediate gear is supported by the stepped portion while the intermediate gear transmits driving force the motor from the drive gear to the feed roller gear during printing.
