摘要： An image forming apparatus includes an image forming unit, first and second rotary shafts, a drive source to rotate at a predetermined low velocity and a predetermined high velocity, a first rotary transmitter connected between the drive force and the first rotary shaft, a second rotary transmitter connected between the drive force and the second rotary shaft, and a drive block member connected between the drive source and the second rotary shaft to block transmission of the drive force to the second rotary shaft when the drive source rotates at the predetermined high velocity. When the drive source rotates at the predetermined low velocity, the drive source drives the second rotary shaft using a difference in torque between an upper limit in high velocity rotation and an upper limit in low velocity rotation greater than the upper limit in high velocity rotation.

摘要： Plural auxiliary rotating members abut at different positions in a circumferential direction of a roller-shaped rotating member that is configured to rotate in a forward direction and a reverse direction. Diameters of a portion of the roller-shaped rotating member where a first auxiliary rotating member abuts and a portion of the roller-shaped rotating member where a second auxiliary rotating member abuts are different from each other. Conveying speeds of sheets conveyed by the first auxiliary rotating member and the second auxiliary rotating member with the roller-shaped rotating member in different directions at the same time are different from each other.

摘要： When starting driving of an agitating unit or a developing roller in an image forming apparatus, rotation speed of one or both of the agitating unit and the developing roller is raised in a stepwise manner until the agitating unit and the developing roller attain a steady rotation speed. When stopping the driving of the agitating unit or the developing roller, the rotation speed is lowered in a stepwise manner until completion of stop of the driving.

摘要： An image forming apparatus includes an apparatus body, a developer container, an outlet, a first shutter, a cover member, a movable member, and a transmission member. The developer container is removably mountable relative to the apparatus body through an opening. The first shutter opens and closes the outlet. The cover member opens and closes the opening. The movable member is reciprocally movable in forward and reverse directions. The transmission member transmits action of the cover member to the movable member and is disposed between the cover member and the movable member. When the movable member is moved in the forward direction, the first shutter is closed. When the movable member is moved in the reverse direction, the first shutter is opened. In a terminal period of an opening operation of the cover member, a movement direction of the movable member is reversed from the forward direction to the reverse direction.

摘要： A sheet feeder incorporatable in an image forming apparatus includes a sheet container to accommodate a sheet, a sheet feeding unit, a sheet conveyance member, a sheet conveying unit disposed downstream from the sheet feeding member in a sheet conveyance direction, and a controller to stop the sheet feeding unit before the sheet abuts against the sheet conveying unit and to resume the driving, and to drive the sheet conveying unit to start while rotating the sheet feeding unit. The controller adjusts a temporary stop period for the driving of the sheet feeding unit before the sheet abuts against the sheet conveying unit, according to a period in which the sheet passes first and second points determined optionally between a standby position determined prior to feeding of the sheet and a temporary stop position located before the sheet abuts against the sheet conveying unit.

摘要： A reciprocating-motion converting mechanism includes a cam that rotates around a rotation center; a reciprocating member that is reciprocated due to rotation of the cam; and a pressing unit that presses the reciprocating member to the cam. A first load torque is generated by a load applied at a point of contact of the cam and the reciprocating motion member. A load applying unit applies a load to the cam to generate a second load torque having a phase substantially opposite to a phase of the first load torque.
