Abstract: The invention provides a toner recovery apparatus, wherein toner on the surface of photoreceptor is removed by a cleaning device and collected in a container. The image forming apparatus includes a stationary member having a toner inlet end and an opposite end. The toner recovery apparatus comprises a driving device for reciprocatingly moving the container along the stationary member. Bumper means are fixed to the stationary member for colliding with the container when the container moves towards the opposite end for applying negative acceleration to stop the movement of the container.

Abstract: In a laser printer or similar electrophotographic image recorder of the type having a photoconductive element subunit including a photoconductive drum and an upper and a lower unit which are hinged together and each is loaded with a different group of structural parts and elements inclusive of the subunit, a device for screening the drum includes a screening member which is movable in interlocked relation to opening and closing motions of the upper unit. The screening member covers the drum when the upper unit is opened and uncovers it when the upper unit is closed. When the image recorder is in operation with the upper unit being closed, the drum is uncovered to allow a laser beam to reach the drum. When the image recorder is out of operation with the upper unit being opened, the screening member covers the drum in response to an opening motion of the upper unit so as to screen the drum against external light.

Abstract: A mask for an electroluminescent panel has an elongated aperture through which a moving photoconductive member is exposed. To prevent elongated side strips from bowing, a connecting strip of mask material runs obliquely to the direction of movement of the photoconductive member. Portions of one or both of the elongated side strips are missing to provide additional exposure to the member to compensate for exposure masked by the connecting strip.

Abstract: Apparatus and method for obtaining a constant copy output rate in color copiers having a transfer station which produces more than one color copy at substantially the same time. The time lapse between making another set of color copies, necessitated by transferring several color image frames in sequence, is utilized to provide the constant output rate. The sheet transport system between the transfer station and the fuser station is controlled such that it delivers the copy sheets to the fuser at time intervals different than that at which they are received from the transfer station. According to the preferred embodiment, the conveyor is stopped for a predetermined time between delivering each sheet to the fuser from the same set.
