    Abstract: An image forming apparatus which forms toner images of different colors by at least one image forming means with a rotatably driven image bearing means, and forms a picture by transferring the different colored toner images formed by the image forming means onto an image transfer medium supported on a rotatably driven endless bearing means, or directly onto the endless bearing means,    the image forming apparatus wherein a latent image writing position on the image bearing means being angularly spaced by approximately 180° from an image transfer position comprising: pattern detecting means for detecting a color misregistration detecting pattern formed on the endless bearing means; and drive control means for individually controlling rotation speeds of rotary means, such as the image bearing means and the endless bearing means, so as to suppress a periodical rotation variation by using detecting information of a vibration component on the periodical rotation variation, which is obtained from detecting signals derived from the pattern detecting means.

    Abstract: In an electronic image printing apparatus of the type in which a light sensitive image recording layer (53) is exposed by a light beam (60,60',60''), an apparatus (57,92,154) is provided for determining and controlling the position of the light beam (60,60',60'') which comprises one or two alternating pluralities of diffraction grating patterns (4,6,8;18,20,22) disposed in a corresponding relationship with at least a portion of the light sensitive image recording layer (53) to produce a diffraction grid (52) which when irradiated by the light beam (60,60',60'') provides a diffracted beam which is representative of the position of the light beam on the diffraction grid (52). The position of the diffracted beam is detected to provide the requisite signal for controlling the position of the light beam (60,60',60'').

    Abstract: An image forming device, such as an LED printer, liquid crystal printer, laser printer or the like, comprises a sheet feeding unit (2), a sheet carrier (22), a pulse motor (12) provided for the sheet carrier (22) and driven to carry a sheet (10) fed from the sheet feeding unit (20) to a printer (16) for printing an image over at least one entire line of a sheet (10), and which is perpendicular to the direction in which the sheet is carried, by one printing operation thereof, a motor controller (14) for controlling the stepping motion of the pulse motor (12) for moving the sheet (10), a printing controller (18) for controlling the printing operation of the printer (16) in such a way that each printing operation thereof is synchronized with the stepping motion of the pulse motor (12), and an outlet tray (24) for receiving the printed sheet (10). Such a device can be of smaller size, and can be cheaper to produce, than previously-­proposed devices.
