ABSTRACT:
An image forming apparatus includes an image bearing member with an image bearing surface adapted to move in a given direction and carry a toner image thereon. A main cleaning device is opposed to the image bearing surface and electrically removes residual toner remaining on the image bearing surface. A power supply is adapted to apply to the main cleaning device a bias having a polarity reverse to a charge polarity of the residual toner. An auxiliary cleaning device is provided near and upstream of the main cleaning device with respect to the moving direction of the image bearing surface and can be brought into contact with the image bearing surface. A support structure supports the auxiliary cleaning device and permits the auxiliary cleaning device to be moved swingingly while following a displacement of the image bearing surface during the moving.
