Abstract
A representative configuration of an image forming apparatus according to the present invention includes a torque meter configured to gauge a rotation load of a photosensitive drum, and a controller configured to control whether to drive a development sleeve when the photosensitive drum is rotated during non image formation or control a driving speed of the development sleeve when the photosensitive drum is rotated during non image formation, based on a difference between first dynamic torque of the photosensitive drum when the development sleeve is rotated at a first speed and second dynamic torque of the photosensitive drum when the development sleeve is stopped or when the development sleeve is rotated at a second speed smaller than the first speed.
