IPC: G03G15/16
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To appropriately adjust the press-contact force between a transfer roller and a photoreceptor in accordance with an output image. SOLUTION: A printing controller 19 fetches information of the output image outputted from a host computer 20 to judge the image at this time and outputs a driving amount signal for bringing the transfer roller 5 into contact with the photoreceptor 1 with the press-contact force corresponding to the judged image, to a driving signal device 18. Then, a movable member 17 is vertically moved by a specific amount, based on the driving amount signal. Then, freely movably connected pressure varying shafts 15a and 15b are vertically moved by using supporting members 16a and 16b as supporting points, to elastically expand and contract pressurizing springs 14a and 14b, so that the transfer roller 5 connected to a rotary shaft 11 pivotally supported by bearings 12a and 12b is adjusted to come into contact with the photoreceptor 1 with proper press-contact force.  Thus, an excellent image without a void, pitch unevenness, a blur, etc., can be outputted.
