    摘要: A drive transmitter, which is includable to a process unit and an image forming apparatus, includes a first gear, a second gear, and a rotation regulator. The first gear has at least one tooth. The second gear has multiple teeth, one of which is meshed with the at least one tooth of the first gear and rotated with the first gear. The first gear continuously rotates and the second gear remains stationary when not in mesh. The number of rotations of the second gear per unit time is smaller than the number of rotations of the first gear. The rotation regulator regulates rotation of the second gear such that a tip of the second gear meshing with the first gear is located downstream from an intersection start point in a rotation direction of the second gear and upstream from an intersection end point in the rotation direction.

    摘要: An image forming apparatus includes an image carrier; a movable endless belt member forming a nip between the image carrier; and a transfer roller made of metal contacting the belt member at a region corresponding to the nip. At the nip, a toner image on the image carrier is transferred onto the belt member. The transfer roller slidably rotates in bearings supporting its shaft. Members having a higher friction coefficient than that of the transfer roller are provided at end portions of the transfer roller. F1>F3 and F2>F4 are satisfied, where F1 is a maximum static friction between the transfer roller and the belt member, F2 is a dynamic friction between the transfer roller and the belt member, F3 is a maximum static friction between the shaft of the transfer roller and the bearings, and F4 is a dynamic friction between the shaft of the transfer roller and the bearings.
