Abstract
A cleaning device for an image forming apparatus in which a shock generation device is provided for imparting an impact force to a cleaning blade in an axial direction of a photoconductive member in order to prevent an edge portion of the cleaning blade from accumulating debris such as minute paper powder and toner, and thereby maintain a high quality image. The cleaning device can be controlled so that operation of the shock generation device for providing an impact force to the cleaning blade starts simultaneously as revolution of a photoconductive member starts, such that the foreign materials are effectively removed from a cleaning blade.
