摘要： A cleaning device is disposed substantially vertical above a photosensitive drum for the purpose of constructing a compact electrophotographic printer. The cleaning device includes a housing that accommodates an auxiliary toner conveying part and a sheet-like resilient member. A cleaning brush is also disposed in the housing so that a gap of 1-3 mm is formed between the cleaning brush and the auxiliary toner conveying part and resilient member. During an image forming operation, toner accumulates between the cleaning blade and the cleaning brush and is conveyed upward through the gap between the cleaning brush and the auxiliary toner conveying part and resilient member. The toner drops onto the cleaning brush near the top thereof and is conveyed by the cleaning brush to a screw. The screw discharges the toner from the cleaning device.

摘要： An imaging apparatus such that residual toner on a transfer/conveyer mechanism such as a transfer belt and an intermediate transfer material is effectively removable. High-tension voltage opposite in magnetic polarity (plus) to the charged toner and a photosensitive drum is applied to a discharger 15 provided ahead of a drive member 12 for driving a transfer belt 6. The residual toner on the transfer belt 6 is removed by a brush 21, and the residual foreign substances come in contact with the photosensitive drum 1 and move onto the photosensitive drum 1 before a printing operation is started. The foreign substances are then removed by a photosensitive drum cleaner.

摘要： It has been discovered that a cause of a transfer member winding on an image carrier at the time of transfer is attributable to a discharge in a gap formed between a forward end of the image carrier and a transfer member transporter and is characterized in that the discharge in that gap is ineffectuated by being controlled. An image-forming apparatus capable of preventing not only the winding on the image carrier, but also the fouling of the forward end even when the transfer member is changed in size, is provided by controlling the discharge in the gap. The gap may be ineffectuated by being pressed physically using a guide, thereby preventing the discharge in the gap. As an alternative, the transfer charge amount is controlled in accordance with the position where the forward end of the image carrier passes the transfer element.

摘要： In an image forming apparatus, a length of a transporting passage between an induction roller pair and a reversal roller pair and a length of a transporting passage between the reversal roller pair and a feed roller pair are respectively set smaller than the smallest length in the transporting direction of a sheet used in an image forming apparatus. A time till the rotation of the reversal roller pair is switched to the forward rotation after a rear end of the sheet having a length in the transporting passage of 8.5 inch after reversal has passed through the reversal roller pair can be set shorter than a time when a leading end of a succeeding sheet inducted into a pull-in passage reaches the reversal roller pair.
