Abstract
An image forming apparatus includes a photosensitive member; a developing device for developing an electrostatic image formed on said photosensitive member into a toner image; a transfer charger for transferring a toner image from said photosensitive member onto an image receiving member; a non-rotational brush and a rotatable brush for electrically charging toner, which remains on said photosensitive member after image transfer by said transfer charger, to collect the remaining toner into said developing device; a driving mechanism provided with a driving source for rotating said rotatable brush; and a moving mechanism for reciprocating said non-rotational brush by a driving force through said rotatable brush in a direction along an axis of said photosensitive member.
