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 rotary drive device includes a motor including a rotary shaft, a planetary gear mechanism, and a rotation position detector. The planetary gear mechanism decelerates a rotation output of the motor at a reference reduction ratio and includes an outer gear, multistage gears, and an output shaft. The outer gear is fixed to a housing of the motor. The multistage gears are provided inside the outer gear. The output shaft transmits the decelerated rotation output of the motor to an outside of the rotary drive device. The rotation position detector detects a rotation position of the output shaft to control rotation of the motor. The motor, the planetary gear mechanism, and the rotation position detector are combined into a single integrated unit and aligned in an axial direction of the rotary shaft of the motor.

摘要： A common driving source transmits a drive force to a driving unit that drives a feeding unit and a conveying unit. The driving source is a motor that rotates in either of a normal direction and a reverse direction. The feeding unit includes a mechanical drive-blocking mechanism in its driving sequence. The conveying unit includes a two-system driving sequence and a mechanical drive-blocking mechanism in the driving sequence so as to rotate in one direction regardless of a rotating direction of the driving source. A reduction ratio of each driving sequence in the conveying unit is identical.
