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 drive unit, which can be included in an image forming apparatus with peripherals disposed thereto and use a control method therefore, includes an inner rotor brushless DC motor, a driver, a rotation detector, and a controller. The driver supplies power to drive the brushless DC motor. The rotation detector detects an amount and direction of rotations of an output shaft. The controller controls the rotations of the brushless DC motor and obtains a target drive signal of the brushless DC motor externally and a detection signal from the rotation detector and outputs a signal to the driver. The controller controls a speed of rotation of the brushless DC motor by varying the signal output to the driver based on the target drive signal and the detection signal.

摘要： A clutch mechanism comprises a planetary gear unit including input transmission, output transmission, and transmission stopping members. Torque entering the input transmission member is outputted downstream of the planetary gear unit by the output transmission member when the transmission stopping member is fixed and is not outputted downstream when the transmission stopping member is unfixed and entering a rotatable state. A rotation prohibiting target has an engaging target and is integral with the transmission stopping member. A rotation prohibiting member has a supporting shaft, a swingable portion at its one end and an engaging portion at its other end to engage the engaging target to enable the transmission stopping member to exert the stopping function. The engaging portion disengages the engaging target to bring the transmission stopping member into an unfixed state. A damper unit absorbs vibration caused in the rotation prohibiting member during a switching operation.
