    摘要： Example embodiments include a driving device having: a plurality of vibrating members that may vibrate when the vibrating members are driven; and a holding part that may hold the vibrating members. The holding part may include a first member with which one or more of the vibrating members may be brought into contact, and a second member with which one or more of the vibrating members may be brought into contact. The first member and the second member may be partially coupled to each other. A grounding member for electrically grounding a member held by the holding part may be brought into contact with one of the first member and the second member that is more difficult to vibrate.

    摘要： A driving device includes: a plurality of vibrating members that vibrate when the vibrating members are driven; and a holding part that holds the vibrating members. The holding part includes a first member with which one or more of the vibrating members are brought into contact, and a second member with which one or more of the vibrating members are brought into contact. The first member and the second member are partially coupled to each other. A grounding member for electrically grounding a member held by the holding part is brought into contact with one of the first member and the second member that is more difficult to vibrate.

    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 first image carrier; a first image forming unit that forms an image; an intermediate transfer belt; a primary transfer unit that primarily transfers the image onto the intermediate transfer belt; a secondary transfer unit that secondarily transfers the image transferred further onto a recording medium; a second image carrier that transfers the image onto the recording medium; a second image forming unit that forms an image on the second image carrier; a direct transfer unit that directly transfers the image onto the recording medium; a recording medium carriage belt, and a driving roller that drives the recording medium carriage belt; a speed fluctuation detecting unit; and a drive control unit that controls driving of the driving roller so as to reduce the cyclic speed fluctuation of the carriage belt based on a detection result of the speed fluctuation detecting unit.
