发明名称 Image forming apparatus
摘要 An image forming apparatus includes a rotatable image bearing member; a charging member for electrically charging the image bearing member; developing device means for developing an electrostatic latent image formed on said image bearing member into a toner image and for collecting toner from the image bearing member; transfer device means for transferring the toner image onto a transfer material; a brush member rotatable in a direction identical or opposite to a rotational direction of the image bearing member and disposed downstream from the transfer device means and upstream from the charging member in the rotational direction of the image bearing member, the brush member contacting transfer residual toner while being supplied with a DC voltage of an opposite polarity to a normal charge polarity of the toner; and a moving member for moving the toner in a rotational axis direction of the brush member while contacting the brush member.
