PURPOSE:To simplify the structure of a chassis, and also, to raise the pressing force for a fixation, by providing one piece of fixing roller and two pieces of pressure rollers which contact so that the pressing force works on this fixing roller. CONSTITUTION:A fixing roller 18 is provided between the upper pressure roller 26 and the lower pressure roller 27. These respective rollers are supported by the upper bearing 30 and 31 through a pressure arm plate 29 which has been attached to a chassis 28, and the upper bearing 30 is energized downward by a compression spring 32. By a form guide 33, a copying form 8 goes in as indicated with an arrow from the lower direction, and discharged as indicated with an arrow from the upper direction. In this way, the recording form 8 which has been taken out by a feed paper roller 15 from a cassette 9 is carried in the direction of a form tray 14 by a carrying roller 17, passes through a development/transfer process and pressured two times in a pressure fixing device, and its fixation is executed exactly.
