摘要： An image forming apparatus includes a primary transfer device that primarily transfers a first image from a first image bearer onto a first belt unit at a primary transfer position, a secondary transfer device that secondarily transfers the first image from the first belt unit onto a printing medium at a secondary transfer position, and a direct transfer device that directly transfers a second image from a second image bearer onto the printing medium at a direct transfer position. A second belt unit is rotatably suspended by plural second rollers and carries and conveys the printing medium through the direct transfer position and the secondary transfer position. An interval between the direct transfer position and the secondary transfer position is prescribed natural number times of a circumference of one of the plural second rollers, which fluctuates a velocity of the second belt unit.

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 drive transmission device includes drive transmission members including a detection target gear, a detection device detecting the rotational position of the target gear and including a position detection member and a detection unit, and a conductive protection member protecting the detection unit. The detection unit and the protection member are assembled to the same member to be installed to an external apparatus. If there is a dimensional error in the protection member causing a portion of the protection member closest to the target gear to shift in position relative to the detection unit beyond a predetermined range, the protection member comes into contact with the detection unit in the assembling process, and is corrected in shape by the detection unit, with the shift in position relative to the detection unit of the portion of the protection member closest to the target gear kept within the predetermined range.
