PURPOSE:To improve transferring efficiency of toner, and to obtain a good image with high image density without void by providing a transfer material pressuring member which brings the transfer material into close contact with a toner thin layer in an opening part of a corona charger. CONSTITUTION:A pair of pressuring materials 13 is provided in both edge parts of the opening part 12 of a transferring charger 11, and the transfer mate rial is brought into close contact with the photosensitive toner thin layer in the opening part of the transfer charger by this pair of pressuring members 13. In definite terms, the pressuring members 13 consisting of an insulated film provided with elasticity are attached in a position retaining both edges of the passed transfer material to form protruding parts 14. These protruding parts 14 are deformed to a state so that they make pressurized contact with the transfer material 33 through the toner thin layer 32, matching the shape of cercumferential face 31 of an electro conductive drum, and the transfer material 33 and the toner layer 32 are sufficiently in close contact with each other. Thus transferring efficiency is greatly improved. |
