摘要： In an image forming apparatus where a transfer roller is arranged to be out of contact with a photoreceptor drum, a guide member for guiding a transfer sheet so as to abut the photoreceptor drum at a predetermined angle and an auxiliary guide member for supporting the transfer sheet to prevent the rear end of the transfer sheet separated from the end of the guide member from being weighed down are arranged close to the photoreceptor drum. Further, to supply a conveying force to the transfer sheet until the rear end of the transfer sheet is separated from the guide member, a conveying roller is arranged opposite to the upper surface of the guide member where the transfer sheet passes.

摘要： A transferring apparatus transfers a toner image formed on the surface of a photoreceptor drum onto a sheet. The photoreceptor drum surface and a transfer roller are arranged in such manner that a gap larger than the thickness of the sheet is left between the photoreceptor drum and transfer roller, and a lower guide member for guiding the sheet in such direction that the sheet abuts the drum surface at a predetermined angle is arranged between a resist roller pair and the drum. The sheet which abuts the drum surface by way of the upper surface of the guide member is in close contact with the drum surface while being bent and deformed along the drum surface. A conveying roller is provided, opposite the upper surface of the lower guide member, with a predetermined gap between, at a position close to but out of contact with the drum surface. The conveying roller may also be arranged to contact the transfer roller.

摘要： An image-forming machine equipped with a transfer device of the type not using a transfer corona discharger is disclosed. A charge supply member is disposed opposite to an image forming member on whose surface a toner image is to be formed, and at a greater distance than the thickness of a transfer material from the image forming member. A voltage of a predetermined polarity is applied to the charge supply member. In a transfer zone, the surface of the transfer material is brought into contact with the surface of the image forming member, while the back of the transfer material is not contacted with the surface of the charge supply member.

摘要： This invention relates to an image forming apparatus and a method for assembling the apparatus. A main body of the image forming apparatus has a frame main body consisting of an optical frame and a chassis made of a resin (resin chassis). Mounting an image recorder unit on the resin chassis improves the precision in mounting the image recorder unit, while the optical frame assuring the rigidity of the apparatus as a whole. The resin chassis consisting part of the frame main body reduces the production cost of the frame main body, in turn, reducing the production cost on the final product, i.e., image forming apparatus.
