Abstract
An image forming apparatus for injection charging which uses charging accelerating particles in a charging nip portion to rotate an image bearing body and a charging roller at different velocities and applies a bias in image forming which is different from a bias applied in non-image forming to feed substantially only the charging accelerating particles in non-image forming, thereby it is possible to enhance a charging property and to provide a favorable image.
