  • Publication number: 20230096244
    Abstract: An image forming apparatus according to the present disclosure includes a skew correction device and a cleaning device. The skew correction device includes first conveying rollers. The first conveying rollers are rotatable about a predetermined rotation fulcrum. The first conveying rollers are, before a sheet, which is skewed, enters a device body, rotated from an initial position, and, when the sheet enters the device body, rotated back to the initial position while nipping and conveying the sheet. The cleaning device includes a toner conveying member that conveys residual toner on an image-carrying member to a predetermined container. Both the first conveying rollers and the toner conveying member operate by consecutively receiving a rotational driving force from a common electric motor.

  • Patent number: 11327428
    Abstract: Provided is an image forming apparatus that together with being able to suppress rotation unevenness is capable of preventing unexpected downtime due to a broken belt. A guide member guides the swing of a swing gear on an arc that connects a first position where the swing gear is engaged with an idle gear, and a second position where the swing gear is not engaged with the idle gear. A transmission cutoff mechanism cuts off transmission of a drive force transmitted to a driven pulley via a belt to a driven shaft when a motor rotates in the reverse direction. A control unit, in a case where rotation unevenness meets a condition, causes the swing gear to swing to the first position by reverse rotation of the motor, which causes the drive force to be transmitted to the driven shaft.
