Abstract
An image forming apparatus includes an image bearing member, a charging station, an exposure station forming an electrostatic latent image on the charged image bearing member, and a developing station for developing the latent image formed on the surface of the image bearing member. A stop control device is provided for immediately stopping a charging operation by the charging device when the image forming apparatus must stop due to the detection of an irregular state during an image forming process. The image bearing member continues moving by at least the distance along that member from the charging to the developing station before the stop control device stops the developing operation and the moving of the image bearing member.
