    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: 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 device is provides, which comprises a body to be scanned that moves in a sub-scanning direction; a writing means for scanning the body in a main scanning direction with a light beam according to image information to form a reference image on the body and repeating the scanning plural times to form plural images; and a second body on which the plural images are overlaid to form a color image. The writing means starts writing the reference image at a start time ty1 when a main scanning synchronizing signal is firstly generated by the writing means after a time tx1 when a predetermined time has lapsed from detection of an image forming start signal of the sub-scanning direction for the reference image. A start time for an image other than the reference image is changed depending on the start time of the reference image.

    摘要: An image forming system and method form temporarily attached color particles corresponding to an image on an intermediate image transfer device. The color particles are temporarily attached to the intermediate image transfer device by supplying energy, such as optical or thermal energy, corresponding to image signals, where the source of energy is located on the reverse side of the intermediate image transfer device from the side on which the particles are temporarily attached. Finally, an adhesion device transfers the color particles corresponding to the image from the intermediate image transfer device to a printing sheet and fuses the image into the printing sheet.
