摘要： 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.

摘要： A belt driving controller is disclosed. The belt driving controller executes driving control of a belt that is wound around plural sustaining rollers by controlling a driving sustaining roller that transmits driving force to the belt. The belt driving controller executes the driving control of the belt by controlling the driving sustaining roller so that a moving velocity fluctuation of the belt caused by a PLD (pitch line distance) fluctuation in the belt circumference direction becomes small, based on rotation information of rotation angle displacement or rotation angle velocities of two sustaining rollers in the plural sustaining rollers, in which two sustaining rollers, the diameters thereof are different from each other and/or the degrees to which the PLDs of parts of the belt which wind around the two sustaining rollers influence the belt moving velocity and the rotation angle velocities of the two sustaining rollers are different from each other.

摘要： A rotational speed of a first roller and a time required for a second roller to make one rotation are measured. A controller calculates an amplitude and a phase of fluctuation in a rotational speed in one rotation period of the first roller while the first roller is rotated by a predefined angle based on the speed and the time. The controller corrects measured speed of the first roller based on the amplitude and the phase, and controls a driving roller based on corrected speed.
