Abstract:
A decelerator for reducing a speed of rotation of a drive source and transmitting drive of the drive source to an image bearing member of an image forming apparatus includes a drive shaft, a drive transmission member, and a pressure regulator. The drive shaft is rotated by the drive source. The drive transmission member is rotated by the drive shaft and includes a peripheral surface that contacts the drive shaft. The pressure regulator presses the drive shaft against a center of rotation of the drive transmission member and includes an alignment regulator to regulate alignment of the drive shaft in a direction of rotation of the drive transmission member. A drive device for rotating an image bearing member includes a drive source including a drive shaft, and the decelerator. An image forming apparatus includes the drive device and an image bearing member rotated by the drive device.
