摘要： The apparatus comprises a driving mechanism for reciprocating a slider having a contact glass thereon, and a rotation control member which is associated with the driving mechanism and which makes one rotation per two rotations of a photoconductor drum and one reciprocating cycle of the slider. Through the rotation control member, a copying process can be controlled in association with the rotations of the photoconductor drum. The slider can be reciprocated freely when the copying machine is not in operation by the present known slider reciprocating driving apparatus. A stopper for stopping the forward movement of the slider without causing any adverse shock is provided.

摘要： An image forming apparatus includes an intermediate transfer member, a sensor, and two image forming units. Each of the image forming units includes an image carrier, an image writer, two development rollers, and a switcher. The image writer writes an electrostatic latent image on the image carrier. Each of the development rollers selectively driven by the switcher visualizes the electrostatic latent image to form toner images in four colors. The toner images are transferred and superimposed onto the intermediate transfer member to form a color toner image. The color toner image is transferred onto a transfer sheet. One or more marks are formed on the intermediate transfer member. The sensor detects one of the marks. The image writer starts writing in synchronism with a sync clock signal of the image writer output immediately after the sensor detects the mark or output after a predetermined time period elapses after the sensor detects the mark.

摘要： An image forming apparatus capable of decreasing the image unevenness of a superimposed image at the time of forming starting (head) lines of the images in respective colors with different beams in order to decrease a shift of a superimposed image. Let a position, where an image in a first color is formed with a beam A as a leading beam, be (a). Let a starting position of formation of an image in a second color be (b), and one dot (line) of shift arises in the superimposed image. In order to decrease the shift of the superimposed image, image formation is performed with selecting a beam B as a beam which writes a head of the image (c). When image formation is performed for color shift reduction with changing a leading beam for each color image, tonality correction is performed to each beam for subsequent images so as to decrease image unevenness due to the difference between shapes and exposure power of respective beams.

摘要： The sheet separation apparatus for separating a transfer sheet from a toner image bearing photoconductor for use in an electrophotographic copying machine comprises a plurality of separators which are rotatably mounted on a shaft arranged parallel to the photoconductor, and each of the separators is independently urged into pressure contact with the surface of the photoconductor by a spring member through a control member which is substantially integral with the shaft. In one embodiment of the sheet separation apparatus, the control member serves as a protector for preventing toner particles from being scattered from the surface of the photoconductor and in another embodiment of the sheet separation apparatus, the shaft can be turned about a predetermined point of one end portion of the shaft in the direction that the other end portion of the shaft can be moved away from the photoconductor for easy maintenance of the sheet separation apparatus.

摘要： A clamp which spans a pair of endless chains grips the leading edge of a sheet to convey the same into engagement with a photoconductive drum of an electrostatic copying machine or the like. A primary feed roller is driven through one rotation to feed the top sheet from a stack into the bite of the clamp. A cam follower actuated by a cam integral with the primary feed roller moves a release member into engagement with the clamp to open the same and further disengages secondary feed rollers between which the top sheet passes from the stack to the clamp. At the completion of rotation of the cam, the cam follower disengages the clamp to grip the leading edge of the sheet and engages the secondary feed rollers to feedingly grip the sheet. The secondary drive rollers are interconnected with the chains for integral driving movement after the sheet is gripped by the clamp and secondary feed rollers.
