Abstract
An image forming apparatus in which when toner remaining on a development roller in an area from a developer nip to a regulating blade disposed upstream of a rotation direction of the development roller during a stoppage of the image forming apparatus passes through the developer nip, a bias is applied so that the toner is drawn to the development roller, and a relative speed difference between the photosensitive drum and the development roller is created so as to be larger than the that during an image forming operation.
