Abstract
An image forming apparatus is provided with: a controller capable of changing a developing bias, which is to be applied to a developing roller configured to carry developer thereon; a peripheral speed ratio of a developing roller to a photosensitive member; a control method by the controller, and a program for operating the controller. A configuration is provided where the developing roller makes contact with the photosensitive member when a developing bias is made to be lower during the non-developing than during a developing phase. The configuration can suppress press fogging at room temperature and low humidity conditions.
