ABSTRACT:
An image forming apparatus includes an electrostatic image bearing member for bearing an electrostatic image; a developer carrying member for carrying developer containing toner; a voltage source for applying to said developer carrying member, an oscillating voltage of a predetermined frequency: a toner image forming device for forming a toner image on said electrostatic image bearing member using said voltage source; a transferring device for transferring the toner image onto transfer material; and a removing device for removing, using said voltage source, the toner remaining on said electrostatic image bearing member after the use of said transferring device: the voltage satisfies: ##EQU1## frequency of oscillating voltage electrostatic image bearing member and DC component of oscillating voltage developer carrying member.
