    摘要: An image forming apparatus includes a recording medium transport belt which is suspended by a plurality of roller members. An image is secondarily transferred from a first image carrier through an intermediate transfer body to a recording medium. An image is directly transferred from a second image carrier to the recording medium. The image forming apparatus further includes a pattern image sensing unit which senses a pattern image transferred from the first image carrier and the second image carrier finally to the recording medium transport belt. Each of a distance from a secondary transfer position to a sensing position and a distance from a direct transfer position to the sensing position in a recording medium transport belt rotation direction is a natural number times a circumferential length of a roller member causing a speed change in the recording medium transport belt among the plurality of roller members.

    摘要: A sheet processing apparatus includes a conveyor, a processing tool, a processing-tool contact-and-separation device, a processing-tool moving device, and a processing-tool facing device. The conveyor conveys a sheet. The processing tool processes the sheet. The processing-tool contact-and-separation device brings the processing tool into contact with the sheet and separates the processing tool from the sheet. The processing-tool moving device moves the processing tool in an intersecting direction intersecting a conveyance direction of the sheet. The processing-tool facing device faces the processing tool with the sheet interposed between the processing-tool facing device and the processing tool. The processing-tool contact-and-separation device includes a regulating member configured to regulate movement of the sheet in a different direction from both the conveyance direction and the intersecting direction.
