Abstract
An image forming apparatus starts a separation operation of separating at least one of a plurality of image bearing members and an intermediate transfer member from each other at a first speed, and when the at least one of a plurality of image bearing members and the intermediate transfer member are not separated from each other within a predetermined period of time from the start of the separation operation, the image forming apparatus performs the separation operation at a second speed lower than the first speed. With such a configuration, even when a sudden load to the separation motor occurs, a load increases due to aging degradation, etc., the occurrence of a separation operation failure of the intermediate transfer belt may be reduced to increase the service life of the image forming apparatus.
