Abstract

PURPOSE: To simplify the device, and also, to cancel a working error of parts by using deflection restoring force of a cam follower shaft as pressure force of a developing roller, and also, constituting the device so that a distribution of the pressure force can be adjusted.
CONSTITUTION: Between a large diameter roller 21 and a small diameter roller 22 of this device, developing paper and microcapsule paper are superposed and fed in. In this case, cams 23a - 23c provided on a cam shaft 25, and bearings 26a - 26c on a cam follower shaft 27 are brought to press-contacting and the shaft 27 is brought to elastic deformation. Subsequently, its restoring force is transferred to the roller 22, and used for transferring an image to the developing paper. Also, by varying a position on a cam outline curve of each cam by rotating the shaft 25 by a desired angle, and varying a distance between its position and the axis center of the shaft 25, or varying a distance between the shafts 25, 27 by wedges 29a, 29b, a pressure distribution to the roller 22 is adjusted.
