Patent ID: 10359717

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.
