Abstract

PURPOSE: To reduce the shock and drive forque upon insertion and discharge of copy paper by forming a clearance, which is larger than the maximum diameter of toners and smaller than the elastic deformation thickness upon pressure fixation of the copy paper, when the upper and lower rigid rollers are stopped for fixation.
CONSTITUTION: Bearings 11 and 12 having a larger diameter than the center portions of upper and rollers 1 and 2 are mounted on the both ends of the rollers 1 and 2 such that a clearanced is formed between the rollers 1 and 2. The clearance d is made larger than the diameters of the toners and smaller than the elastic deformation thickness upon the pressure fixation of copy paper. Thus, when the copy paper P is inserted, the roller spacing is widened to b so that the shifts of the rollers with respect to a pressure spring 8 are b - d and d1, respectively. In other words, as compared with the one, in which the rigid rollers are in contact, the shifts can be reduced by d. As a result, the shocks upon insertion and removal of the paper can be reduced together with the drive torque.
