PURPOSE:To reduce the unevenness of printing pitches, and to prevent the generation of displacement among each recording paper by installing a motor coupled with a photosensitive drum by a revolution transmission mechanism at a specified reduction gear ratio to a drive for the photosensitive drum and a paper feeder for recording and providing an exposure means with a recording-start position control means recording picture information from the reference location of the drum. CONSTITUTION:A paper feeder for recording is separated into a paper feeder extracting, positioning and supplying recording paper 41 and a paper delivery device carrying supplied recording paper 41, and the paper delivery device is driven by the same motor 51 as a photo-sensitive drum 11. In a drive, ¦n-m¦<=0.125 holds in relationship with an integer (m) closest to an integer (n) at the reduction gear ration 1:n of a revolution transmission mechanism coupling the phot-sensitive drum 11 and the motor 61. An exposure means is provided with a recording-start position control means, the control means sets the start timing of the recording of No. 1 picture information to the photosensitive drum as the reference location of the drum, and No.2 start is controlled by a timing means based on No.1 start timing. Accordingly, the unevenness of printing pitches is reduced. |
