    摘要: An image production apparatus includes at least one image production unit having a latent image forming device for forming a latent image on an image carrying member and a developing device for attaching toner to the latent image formed by the latent image forming device. A toner image formed by the image production unit is transferred to a transfer medium to produce an image. The image production apparatus further includes a periodicity giving device for giving periodicity to movement in a main scanning direction of the image carrying member or transfer medium. According to this periodicity, the movement time from an image forming position to a transfer position, or the movement time of a transfer medium between adjacent transfer positions is set equal to an integral multiple of the period.

    摘要: An image recording apparatus for recording a two-color image on both surfaces of a continuous recording medium includes a toner image recording portion which has a toner carrier and transfers a toner image formed on a surface of the toner carrier onto the recording medium, a tractor for feeding the recording medium on which the toner image is transferred, and a both side fixing machine for receiving the recording medium fed by the tractor to fix the toner image transferred on the recording medium. In this image recording apparatus, guide rollers come into contact with non-printing portions on both side ends of the recording medium to apply tension to the recording medium by a spring and thereby gives a predetermined slack to the recording medium to absorb a difference in speed resulted between the tractor and the both side fixing machine.

    摘要: A printing system has a first printer apparatus for forming an image on a first plane of a web having no feed holes and a second printer apparatus provided at a post stage following the first printer apparatus for forming an image on a second plane of said web. The first printer apparatus (P1) is operable to form a position-alignment mark (Rm) at a predesignated position on each page of a web. This position-alignment mark is detected by mark detection means of the second printer apparatus (P2). Control means is provided for controlling the web transport speed so that both the generation timing of a web feed control signal (CPF-N signal) being generated with preset cyclic periods and the generation timing of a mark detection signal issued from the mark detection means through detection of the position-alignment mark are kept constant in phase.
