摘要： A process unit includes a rotatable image bearer, an optical writing head to expose the image bearer within an maximum exposure range in an axial direction of the image bearer, a developer bearer, spacers disposed in axial end portions of the image bearer to determine a position of the optical writing head relative to the image bearer and slidingly contact the image bearer, a cleaner disposed downstream from the developer bearer in an image bearer rotation direction, and a remover to slidingly contact the axial end portion of the image bearer to remove a substance adhering thereto. In the axial direction, inner ends of the spacers are positioned inside a toner layer range of the developer bearer extending beyond a largest sheet width. The remover is disposed downstream from the cleaner and crossing a line extending from the inner end of the spacer perpendicularly to the axial direction.

摘要： An image forming apparatus including an image bearing member; a developing device forming a toner image; a toner supplying device including a toner container, a toner feeding passage, a pump, in which a first member is moved while rubbing a second member to feed a developer supplement including at least the toner, and a residual toner detector detecting the amount of the developer supplement remaining in the toner container. Even after the toner container achieves a near empty state, image forming operations are continued as long as a predetermined condition is satisfied while changing the pump's condition such that the pump is stopped, the ratio of the pump stopping period to the pump driving period is set to be greater than that before the near-empty detection, or the pump stopping period and the pump driving period are set to be longer than those before the near-empty detection.
