Abstract:
An image forming apparatus includes: a photosensitive drum; a driving roller that drives a transfer member; a facing roller facing the driving roller; a driver that drives one of the photosensitive drum, the driving roller, and the facing roller; and a hardware processor that: acquires carry-in fluctuation information of speed fluctuation of any one of the photosensitive drum, the driving roller, and the facing roller when a sheet member is carried into the transfer member; detects carry-in fluctuation timing of the speed fluctuation of any one of the photosensitive drum, the driving roller, and the facing roller that occurs when the sheet member is carried into the transfer member; predicts carry-out fluctuation timing of speed fluctuation of any one of the photosensitive drum, the driving roller, and the facing roller that occurs when the sheet member is carried from the transfer member; and performs feedforward control on the driver.

Claim (Index 7):
The image forming apparatus according to  claim 6 , wherein\n a plurality of types of the sheet members is provided, and the hardware processor acquires, in association with the respective types, pieces of carry-out fluctuation information of speed fluctuation of at least any one of the photosensitive drum, the driving roller, and the facing roller when the sheet member is carried from the transfer member, calculates a plurality of correction amounts for performing the feedforward control based on the pieces of carry-out fluctuation information corresponding to the respective types, and according to the correction amounts corresponding to the respective types and based on the carry-out fluctuation timing predicted, performs the feedforward control on the driver to correct the speed fluctuation that occurs when the sheet member is carried from the transfer member.
