    摘要： A multicolor image-on-image reproduction machine includes a main assembly, a controller, a movable image bearing member having a path of movement, and a plurality of air breakdown charge and development (ABCD) imaging units mounted along the path of movement for forming color separation toner images. Each (ABCD) imaging unit includes a photoreceptor having a photoconductive surface forming a toner image separation development nip with the movable image bearing member; a toner supply apparatus for applying a layer of toner onto the photoconductive surface; a charging device for uniformly charging the photoconductive surface through the layer of toner; and an exposure device connected to the controller for image-wise exposing of the photoconductive surface and the layer of toner to form therein image areas and background areas of a desired color separation image. The multicolor image-on-image reproduction machine then includes a bias source for biasing the image bearing member at the toner image separation development nip to a potential sufficient to cause air breakdown selective recharging of the background areas of the layer of toner, thereby enabling the image areas of the layer of toner to be separated and developed as a color separation toner image onto the movable image bearing member, and the background areas thereof to remain on the photoreceptor.

    摘要： Even when recording sheets (P) are fed from different storage means by switching over among a plurality of recording-sheet storage means (106a, 106b, 106c, 106d, 113), recording sheets are fed to image transfer means (101) always at a constant timing, so that the copying operation is executed at high copying efficiency and with reliability. Recording sheets (P) stored in a cassette (106a) are fed one by one to a conveyance path (108a) by a sheet feed roller (109a). The recording sheets (P) retained in an intermediate tray (113) are fed one by one to a conveyance path (115) by a sheet feed roller (114). The timings at which the sheet feed rollers (109a, 114), which are first drive rollers, are driven are controlled in such a way that a register roller (160), which is a second drive roller, can be driven at a constant cycle time with respect to a plurality of recording sheets (P) fed from the conveyance path (108a, 115). Even when the cassette (106a) and the tray (113) are switched over, the register roller (160) is driven always at a constant cycle time. Thus, the image forming operation can be executed by feeding recording sheets (P) in synchronization with the image-reading timing.

    摘要： An image development method and apparatus, wherein a support member (12) is provided with a layer (58) of marking material thereon, and an electrostatic latent image is created in the layer of marking material via image-wise charging of the layer of marking material by a selectively controllable charging device (60) for directing a charge stream toward the support member (12) having the layer (58) of marking material coated thereon. The image-wise charge stream corresponds to the latent image, which, in turn, leads to image-wise charging of the toner layer (58), such that the toner layer itself becomes the latent image carrier. The latent image carrying toner layer is subsequently developed and transferred to a copy substrate (70) to produce an output document.
