发明名称 Image forming apparatus
摘要 An object of the present invention is to provide an image forming apparatus that has an image bearing body, charging device for charging the image bearing body, developing device for forming a developer image by developing, with developer, an electrostatic image formed on the image bearing body, transferring device for transferring the developer image to an image-receiving member, first charge-applying device, provided on a downstream side of the transferring device and on an upstream side of the charging device in a moving direction of the image bearing body, for charging a residual developer remaining on the image bearing body after a transfer effected by the transferring device to a polarity opposite to a normal charging polarity of the developer, and second charge-applying device, provided on a downstream side of the first charge-applying device and on the upstream side of the charging device in the moving direction of the image bearing body, for charging the residual developer charged by the first charge-applying device to a same polarity as the normal charging polarity of the developer, wherein the charging device applies a charge to the residual developer charged by the second charge-applying device.
