Abstract: Provided is an image forming apparatus including an image carrier, a transfer unit, a driver, a hardware processor, an adjustment mechanism, and a speed detector. The hardware processor sets a command value. The hardware processor performs a constant-torque control based on a constant-speed drive torque detected in a constant-speed control. In the constant-torque control, the hardware processor performs a feedback control to set a reference value to an average speed of the driver during passage of a first sheet and calculate a difference from an average speed during passage of a subsequent sheet so as to derive the command value. The hardware processor determines whether a load torque increase, its factor, and/or its influence exceeds a threshold, and forcibly sets the reference value to a speed detected while a pressure between the transfer unit and the image carrier is reduced by the adjustment mechanism from the pressure during image transfer.

Abstract: An image forming apparatus includes the following, a pair of first conveying rollers, a pair of second conveying rollers, a driver which rotates and drives the second conveying rollers by a command value; and a controller which is able to control the driver to perform constant speed control to rotate the pair of second conveying rollers at a constant speed and to perform constant torque control to rotate the pair of second conveying rollers at a constant torque. When the constant torque control is performed, the controller starts the constant torque control with a predetermined initial torque. Based on sheet interval torque detected in a sheet interval term in which the pair of second conveying rollers do not sandwich and convey a sheet after the first sheet reaches the pair of second conveying rollers, the controller corrects the initial torque and calculates a command value for the next sheet.
