    摘要： In a color image forming apparatus, a plurality of color images of component colors are combined to form a full color image. These images of the component colors are overlapped on an intermediate recording medium, and are then transferred to a transfer medium. Control circuitry reduces the amount of time required to form the component color images on the intermediate transfer medium, and to prevent an abnormality such as an out-of-phase or pull-out of a closed loop control circuit for controlling such a formation of the component color images. This may be achieved by abruptly changing a phase of a motor synchronizing signal. Further, for a period of time after the motor synchronizing signal is abruptly changed, a gain of an amplifier in the motor control circuit can be reduced, an abnormality detection in the motor control circuit can be reduced, the motor control circuit can be placed in an open loop state, or an addition or subtraction signal can be input to the closed loop motor control circuit. This specified period can also be detected based on a feedback including a rotational phase of a polygon motor formed as part of a unit for writing the individual component color image signals.

    摘要： A system, method, computer program and apparatus for providing regulating signals for regulating the position of an objective lens relative to a track on a disk. The regulating signals are obtained in response to an access request specifying an access target region on the disk. The tracks of a disc are divided into a plurality of zones, each zone having associated signal regulation information. In response to an access request, the signal regulation information for the zone containing the access target region is used to regulate the position of the objective lens.

    摘要： An apparatus and method of forming a color image on a recording sheet by transferring respective images onto a single recording sheet conveyed by a conveying belt, where the combination of the respective images form the color image. The respective color images are formed with a plurality of electrophotographic processing sections disposed along the conveying belt such that the respective color images are superimposed on one another to make the color image. The electrophotographic processing sections also form more than two colors, of a same pattern, of image positional deviation detecting marks. The image positional deviation detecting marks include a line in a main scanning direction and another line positioned at an incline with respect to the former line in order on the conveying belt. A detector is included that detects the image positional deviation detecting mark with a single detecting device composed of a light source, a slit, and a light accepting element.

    摘要： A full-color image forming apparatus having a photo-conductive belt on which mono-color toner images are respectively formed, an intermediate transfer belt onto which the mono-color toner images are respectively transferred to form a full-color toner image, and a transfer member for transferring the full-color toner image onto a copy sheet. The intermediate transfer belt includes timing marks printed thereon which are detected by a sensor to generate an image forming start signal for each of the first mono-color toner image forming processes. The start signal is generated by a controller only when cleaning of the intermediate transfer belt has completed and the cleaning blade has left therefrom. A timer may be used to delay the starting of the first mono-color image forming process until the transfer belt returns to a normal operating speed after the cleaning blade is removed from the transfer belt.
