摘要： A transfer device includes a belt image bearer; a driving roller that rotates the belt image bearer; a transfer member; first and second driving motors that respectively rotate the driving roller and the transfer member; first and second speed detecting units that respectively detect rotational speeds of the belt image bearer and the transfer member; and a control unit that implements control such that the belt image bearer and the transfer member are rotated at rotational speeds corresponding to a relative speed at which a variation amount is less than a predetermined variation amount, the variation amount being the variation of values of driving torques of the first and second driving motors in a state where the belt image bearer and the transfer member are in contact, with respect to these values in a state where the belt image bearer and the transfer member are separated.

摘要： A rotator control device includes drivers to drive rotators for sheet conveyance, respectively; and a processor including a selector to select, from the rotators, a pair of a first rotator subjected to rotation speed adjustment and a second rotator adjacent to the first rotator, and an acquisition unit to acquire a torque-related value representing a driving torque value of a driver to drive the second rotator or a value proportional thereto. The processor further includes a speed adjuster to adjust a rotation speed of the first rotator to approximate a variation in the torque-related value to zero. The selector selects a subsequent pair after adjustment of the rotation speed, designates the first rotator of the preceding pair as the second rotator of the subsequent pair, and selects, as the first rotator, a rotator adjacent to the first rotator of the preceding pair, opposite the second rotator of the preceding pair.

摘要： A rotating member control device that controls a first rotating member and a second rotating member to convey a sheet includes a processor configured to execute a program to implement processes of controlling the first rotating member and the second rotating member to come into contact or be separated from each other and acquiring a value that corresponds to or is proportional to a driving torque of a first driving unit that rotationally drives the first rotating member. The processor acquires the value upon separation when the first rotating member and the second rotating member are separated from each other and upon conveyance when the sheet is held between and conveyed by the first rotating member and the second rotating member. The processor further sets a rotational speed of the second rotating member such that the value acquired upon separation and the value acquired upon conveyance become equal.
