    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: A power transmission device including coaxially a first rotary body (106) including a first gear on a drive source side, a second rotary body (108) including a second gear on a driven side, a third rotary body (107) including a third gear movably held to transmit a driving force, and a guide member (107f, 106f, 108a) disposed at one of the first gear, the second gear, and the third gear to contact a first end surface of a gear tooth of another of the first gear, the second gear, and the third gear, serving as a mating gear, to guide the first end surface between teeth of the one of the first gear, the second gear, and the third gear. The guide member (107f, 106f, 108a) extends toward the mating gear and a tip of the guide member is spaced apart a predetermined distance from an end of the one of the gears.
