摘要：
This invention relates to an image forming apparatus which has a recording material support member for supporting a recording material and moving therewith, an image forming unit for forming an image on the recording material supported by the recording material support member, and attraction charging devices for electrostatically attracting the recording material to said recording material support member. The attraction charging devices are first and second electrodes positioned across the recording material support member from each other, wherein a center of charging of the first electrode to the recording material support member is shifted from a center of charging of the second electrode, in the moving direction of said recording material support member, and there may also be an auxiliary charger for charging, prior to image formation, the recording material attracted to the recording material support member.
