Abstract
An image forming apparatus equipped with a monochrome mode and color mode, in which the transfer drum is made to rotate without any paper wrapped around it to clean the transfer drum each time a series of copy operations is completed. By controlling the cleaning period through increasing or decreasing the number of non-paper rotations in response to the last copy operation mode, the transfer drum may be adequately cleaned at all times, and the amount of wear on the transfer drum and cleaning device caused by the cleaning operation is reduced.
