An image forming apparatus includes a chassis, a motor, a drive transmission gear that receives rotational force from the motor, a feed roller rotatably supported by the chassis, an intermediate gear that has a circular bearing, receives rotational force from the drive transmission gear, and transmits rotational force to the feed roller gear, and a gear support axle that is inserted through the bearing of the intermediate gear for rotatably supporting the intermediate gear. The gear support axle is provided with a bearing engagement part. The bearing engagement part has at least one flat section, at least one circular section, and at least two support portions formed between the flat section and the circular section, such that the gear support axle is supported by the bearing at at least one of the two support portions.
