Abstract
Provided are a cleaning member that scrapes developer from a photosensitive drum attached to an opening of a cleaning frame, and a transport member that transports scraped developer from an opening side of the frame towards an opposing deep side. The transport member is driven such that an absolute value of maximum acceleration at the time of movement of the transport sheet in a direction from the opening side towards the deep side is smaller than an absolute value of maximum acceleration at the time of movement in a reverse direction of the former direction. In the longitudinal direction of the photosensitive drum, the width of the transport member is smaller than an abutting width of an abutting portion of the cleaning member with the photosensitive drum, and ends of the transport member in the longitudinal direction are positioned inward of ends of the abutting portion.
