PURPOSE:To record an image without causing color slippage by electrically correcting positional deviation in the subscanning direction between the drum driving system and the image write-in system before image writing. CONSTITUTION:This device is constituted so that when the time difference between the position signal 35 and the pulse signal (BD signal 32) is measured by the counter 45, the driving pulse imparted to the pulse motor 50 is controlled from the first transition point (rising) to the second transition point (falling) of the position signal 35 outputted by the interrupter so as to minimize the dislocation in the subscanning direction between the drum driving system and the image write-in system by the microcomputer 43. |
