摘要： A color recording apparatus has an electric charge carrier which is circulatingly movable, an electrostatic latent image forming unit for forming a latent image which corresponds to an original image on the carrier, a development unit for developing the latent image; a transfer unit for transferring the developed image formed on the carrier to a record paper in a transfer process, a conveyor for conveying the record paper forward and backward with respect to the transfer unit, and a control unit which repeats control operations for controlling the latent image forming unit to form a latent image on the carrier, for controlling the development unit to develop the latent image, for controlling the conveyor to convey the record paper forward, for controlling the transfer unit to transfer the developed image to the record paper, and for controlling the conveyor to convey the record paper backward at least for one time. The control unit controls the conveyor prior to the transfer process so that the record paper is positioned at a point which is a predetermined distance before a transfer point and that a forward movement of the record paper is started on the basis of an information signal which is output in response to a state of starting an electrostatic latent image forming operation each time the transfer process is carried out.

摘要： A device for use in electrostatographic image recording equipment for retaining and transporting a paper sheet, document or similar sheet member. A transporting member is implemented as an endless belt. An AC voltage is applied to the belt to form a charge density pattern on the surface of the belt, while the charge density pattern sets up a non-uniform electric field in close proximity to the surface of the belt. The non-uniform electric field urges the sheet member against the belt and thereby allows it to be surely transported by the belt to a predetermined position without being dislocated.

摘要： An image forming apparatus of the type forming a toner image on a photoconductive drum or similar image carrier, transferring it to a paper or similar transfer medium via an intermediate transfer body, e.g., belt, and fixing it on the medium by a fixing device is disclosed. Just after the transfer of a toner image of the last color which is to lie over the other toner images on the intermediate transfer belt, the peripheral speed of the belt is switched to a comparatively low speed matching a fixing and paper transport speed. At this instant, the belt is moved away from the drum. The length of the transfer medium and the distance between a paper transfer position and a fixing position is compared. For a relatively short transfer medium, the peripheral speed of the belt is not switched to the low speed.

摘要： An image forming apparatus having an image carrier for forming an electrostatic latent image thereon, and a plurality of developing units each facing the image carrier and movable toward and away from the image carrier. A developing roller driving mechanism serves two different functions at the same time, i.e., causing any of the developing units to move between a developing and a non-developing position and driving the developing roller associated with the developing unit. When the developing roller driving mechanism is operated, the developing unit is moved to the developing position in the event of development and to the non-developing position in the event of non-development.

摘要： A plurality of feed units feed a copy sheet (13) down a sheet feed path (41) along which various operating units (18), (37) are disposed. The operating units (18), (37) function to transfer and fix a toner image to the copy sheet (13). Sensors (42), (43), (44), (46), (47) sense for the presence of the copy sheet (13) in the feed units at respective times. Absence of the copy sheet (13) indicates that the copy sheet (13) is jammed or stopped in the previous feed unit. In such a case, all feed units downstream of the feed unit in which the jam is sensed are driven to feed out prior copy sheets (13) in the downstream units. All feed units upstream of and including the feed unit in which the jam is sensed are de-energized to enable the operator to clear the jam.

摘要： Upper and lower sheet carriages are rollingly supportable on upper and lower pairs of horizontal rails respectively. Each carriage supports a stack of sheets for a copying machine or the like. A drive comprising endless chains rolls one of the carriages to a lift position above an elevator and the other of the carriages to a loading position spaced from the elevator. The elevator is raised to lift a carriage from the lift position to a sheet feed position above the upper rails. The spacing between the lower rails is sufficiently smaller than that between the upper rails that the lower carriage may be raised through the upper rails by the elevator.

摘要： A duplex tray is provided for an automatic duplex copying machine, or the like, for receiving and stacking thereon one-side-copied and for re-feeding those sheets into the machine in order to perform printing on the other side of each sheet, having, a gate for switching the sheet transportation directions from a sheet path for discharging sheets outside the machine to a sheet path for discharging sheets onto the duplex tray, and vice versa; a tray pressure application member means for moving the tray between (i) a reference position and (ii) a position deviated outwards from the reference position; an inclined roller which is movable upwards and downwards and can line up the sheets discharged onto the tray; whereby, at the time of sheet discharging, the gate is moved to the side of the sheet discharging path of the tray, and the tray pressure application member is moved to a non-pressure application position, and the tray is moved to a position deviated from the reference position and the inclined roller is moved to a descended position. In this duplex tray, by selecting either a sheet discharge mode or a sheet re-feed mode, a single solenoid is energized or deenergized, whereby a single half-turn cam is controlled through a spring clutch, and by that cam, the gate, the tray pressure application member and the inclined roller are displaced through a linkage mechanism to their respective positions for discharging sheets onto the tray or for re-feeding sheets.
