Abstract:
An image forming apparatus comprising:an image bearing member;a movable intermediary transfer member;voltage applying means for applying a voltage to said intermediary transfer member to sequentially effect overlapping transfer of a plurality of toner images from said image bearing member to said intermediary transfer member at a transfer position, wherein the plurality of toner images are transfer onto a transfer material from said intermediary transfer member; andcontrol means for controlling the voltage applied to said intermediary transfer member from said voltage applying means such that an absolute value of the voltage in larger than the voltage for transferring a first toner image from said image bearing member onto said intermediary transfer member, when the first toner image on said intermediary transfer member passes through the transfer position in a period which is after the first toner image is transferred from said image bearing member onto said intermediary transfer member and which is before a second toner image next to the first toner image is transferred onto said intermediary transfer member.
