ABSTRACT:
An apparatus for reducing an image forming time period includes a rotatable image bearing member, a charging device for charging the image bearing member, an image forming device for forming an image on the image bearing member which was charged by the charging device, a transfer material bearing member for holding a transfer material and for conveying the transfer material to a transfer station regarding the image bearing member, a transfer device for electrostatically transferring the image formed on the image bearing member onto the transfer material held by the transfer material bearing member at the transfer station, and a restraint device which prevents the charge on the transfer material bearing member from being transmitted when an area on an image bearing member which is to be compacted with the transfer material held on the transfer material bearing member during image transferring is situated at the transfer station before an operation of the transfer device is started. In the present apparatus, the charging is effected by the charging device, image formation is effected by the image forming device, and image transferring is effected by the transfer device being started during the same one revolution of the image bearing member.
