Abstract:
1. An image forming apparatus, comprising: an image bearing member; charging means for charging said image bearing member; developing means for developing an electrostatic latent image with a developer to form a developer image; first auxiliary charging means, for charging a residual developer remaining on said image bearing member, disposed downstream from a transfer position where the developer image is transferred onto an image receiving member and upstream from said charging means, in a movement direction of a surface of said image bearing member; and second auxiliary charging means, for charging the residual developer, disposed downstream from said first auxiliary charging means and upstream from said charging means in the movement direction of the surface of said image bearing member; wherein said first auxiliary charging member is supplied with a DC voltage of a polarity opposite to a normal polarity of the developer and with an AC voltage, and said second auxiliary charging member is supplied with a DC voltage of a polarity identical to the normal polarity of the developer.
