Abstract:
An image forming apparatus comprising:an image bearing member for bearing a toner image;transfer means for transferring the toner image from said image bearing member onto a transfer material;a charging member for contacting to a surface of said image bearing member from which residual toner is not removed to electrically charge said image bearing member, said charging member being capable of temporarily collecting the residual toner;cleaning means for applying, to said charging member, a cleaning voltage for returning the residual toner to such an area of said image bearing member as is going to be a non-image area, the cleaning voltage being different from a charging voltage which is applied to an area of said image bearing member as is going to be an image area;image forming means for forming an electrostatic image on said image bearing member having been charged by said charging member;developing means for developing the electrostatic image on said image bearing member and for collecting the residual toner from said image bearing member; andcontrol means for controlling said cleaning means to vary a cleaning condition of said charging member.
