摘要： An image forming apparatus includes a transfer belt onto which a toner image formed on an outer surface of a photosensitive medium is transferred. The transfer belt moves along a predetermined closed path while being supported by a plurality of rollers. A protection unit protects the transfer belt by being attached to at least one of an inner surface and an outer surface of a non-transferring region of the transfer belt. A control unit controls the transfer belt so that an overlapping part where the protection unit is attached to the transfer belt, and a seam part where two ends of the transfer belt are connected stops at a predetermined location after printing. The image forming apparatus substantially prevents partial loss of an image by preventing wrinkles in the transfer belt.

摘要： An transfer belt for use in an image forming apparatus that senses an initial printing position. The belt includes a PC alloy portion, protective tape, and an error prevention section. The PC alloy portion includes a position sensing hole extending therethrough and disposed proximate to an edge of the PC alloy portion. The PC alloy portion is usable to determine an initial printing position. The protective tape is attached to upper sides and lower sides of both edges of the PC alloy portion. The error prevention section is insertable into the position sensing hole and has a thickness substantially equivalent to the PC alloy located around the position sensing hole.

摘要： A printing method and apparatus clamps a sheet of printing paper at a first position of a drum supplied with the printing paper. The printing paper is released from a clamped state at a second position just in front of an initial printing position. While unclamped, the leading edge of the printing paper is transferred to the initial printing position, so that printing is started from the leading edge and the printing paper is again clamped at a third position which is located beyond the initial printing position. Therefore, printing is performed from the leading edge of the printing paper, which results in printing without any margins. Also, a plate spring presses the printing paper toward the drum just in front of the printing position where the print head, applies pressure for printing. The plate spring elastically applies pressure to the printing paper to transfer the printing paper to the printing position while in contact with the drum.
