    摘要: An image processing apparatus eliminates a detection error in a color offset detecting operation due to a periodic fluctuation in a speed of a conveying belt which conveys a transfer sheet on which color component images are transferred and superimpose to form a multi-color image. A plurality of image forming units are arranged along the conveying belt, each of the image forming units transferring a color component image on the transfer sheet and also transferring a register mark on the conveying belt. A register mark detecting sensor located along the conveying belt detects the register mark on the conveying belt. A distance between the register mark detecting sensor and one of the plurality of image forming units adjacent to the register mark detecting sensor is a multiple of an integer of a circumference of the drive roller. A distance between adjacent ones of the plurality of image forming units is a multiple of an integer of the circumference of the drive roller.

    摘要: An image forming apparatus includes a plurality of image formation units which print an image of different color on a paper and also form positional deviation detection marks and image density regulation marks, on a conveyer belt or on at least one of a recording medium and an intermediate transfer body that conveys the paper, when such a request is received. When requests for formation of the positional deviation detection marks and the request for the formation of the image density regulation marks is received at the same time or at substantially the same time, the main CPU orchestrates the conveyer belt and the image forming units to form the positional deviation detection marks and the image density regulation marks in continuation.

    摘要: An image forming apparatus includes an image carrier, a toner-image forming unit, a transfer unit, a cleaner, a plurality of cylindrical transport path forming members, a falling transport path forming member, and a discharge port. The falling transport path forming member has through holes in a side wall thereof. A second end of each of the transport path forming members is inserted into a corresponding one of the through holes. The falling transport path forming member forms a falling transport path that causes toner ejected from an ejection port disposed in the second end to fall. The discharge port is disposed in a lower part of the falling transport path forming member to discharge the toner to a discharge destination. The second ends of the transport path forming members are disposed offset from each other in a horizontal direction on the side wall of the falling transport path forming member.

    摘要: Tray means for stacking sheets, pickup means for separating and for conveying sheets into a single sheet on the tray means, and sheet conveyance means for conveying a sheet separated by the pickup means to a predetermined processing position are provided. Projecting guide means project from a sheet support surface of the tray means into a notched opening of the sheet is provided; and an oblique surface is formed to prevent a trailing side edge of the opening from catching on a leading side edge of the opening of a lower sheet when feeding an uppermost sheet to the projecting guide means. This makes it possible to feed only the uppermost sheet downstream without an opening edge formed in the uppermost sheet from interfering with an opening edge of a lower sheet.
