Filed: 1988-04-09
Abstract: PURPOSE:To form an overlap image being free from a shift of each image by positioning the transfer paper which is brought to reciprocating motion by a carrying means and to which each color image is brought to overlap transfer, in a prescribed reference position before the transfer. CONSTITUTION:A carrying belt of a carrying means for bringing the transfer paper to reciprocating movement is driven by a driving motor 2315, a photosensitive belt is driven by a driving motor 2113 and each color image is brought to overlap transfer onto recording paper. Also, the motor 2315 contains a counter part by which a long period pulse outputted from an encoder 2317 counts a pulse which is interpolated by a short period pulse outputted from an encoder 2316, and brought to feedback control by a servo-control board 253 to which a pulse from an encoder 2114 is also supplied. In such a way, the transfer paper before the transfer is positioned in a reference position of a prescribed distance of the return carrying side from a transfer position by synchronizing exactly with the photosensitive belt without being influenced by noise, etc. As a result, an overlap multicolor image of a good quality being free from a shift in each color image is formed.
