Abstract: Paper-feed control of an image-forming apparatus, in which the control unit has a paper-feed-motor-drive-controller for controlling a paper-feed-motor. The paper-feed-motor rotating a resist roller and a paper ejection-roller for feeding printing paper. The paper-feed-motor is controlled to perform a plurality of paper-feeds of predetermined width on a sheet of printing paper. An image is formed on the sheet of printing paper after respective paper-feed. The paper-feed-motor is controlled by the paper-feed-motor-controller to perform the paper-feed such that the end of the printing paper remains in contact with the resist roller from which the end of the paper leaves after the final paper-feed.

Abstract: A toner image which is carried by a photosensitive endless belt is pressed against a printing paper by a transfer opposed roller provided inside the photosensitive belt to transfer the toner image onto the printing paper, and the image transferred onto the printing paper is fixed. The position of the transfer roller which is moved inside the photosensitive belt is detected by a detector. When the detected position agrees with a predetermined position, the moving direction is reversed by a control unit and the moving distance of the transfer roller is varied in accordance with the size of the image ad, further, the contamination of the backside of the printing paper is avoided.

Abstract: An image forming device and an image forming method for transporting a toner image on an endless belt shaped toner image transporting member. The toner image transporting member is supported by a plurality of rollers and is stretched out and made rotatable in the same direction as the recording medium is transported. The colored toner is transported on the outside of the toner image transporting member and is transferred onto stationary recording medium by an opposed image transferring roller while the rotation of the toner image transporting member is suspended. The image transferring process is repeated for the required number of colors.

Abstract: A transverse-type image forming apparatus in which a toner image carried on an endless toner image carrying belt is transferred to a printing paper by a transfer facing roller provided inside the toner image carrying belt and caused to move along the printing paper. A transfer bias voltage is applied to a transfer plate, on which the printing paper is set, during the backward movement of, or during both the forward and backward movements of, the transfer facing roller, so as to cause the toner image to be electrostatically attracted to the printing paper. The uneven transfer of the toner image is reduced.

Abstract: A support member has a plurality of through-holes for supporting printing paper to which a fusible toner is adhered. Hot air is blown toward the printing paper. By releasing a considerable amount of hot air blown toward the support member downward through the through-holes, the amount of hot air bouncing on the surface of the support member is decreased. Thus, floating or fluttering of the leading end of the printing paper is prevented when the leading end of the printing paper rushes into the fixing apparatus.

Abstract: A toner image onto a print form by pressing a photosensitive material belt against a transfer plate through movement of a transfer opposite roller. The photosensitive material belt running in a direction orthogonal to the supply direction of the print form on a transfer plate. The photosensitive material belt is stably maintained at a region completed for transfer in an attitude following the upper surface of the print form.

Abstract: An image display unit including an endless transfer belt that is tensioned by a plurality of rollers. A toner image carrier is tensioned in a direction orthogonal to the rotational direction of the transfer belt. An image formation system provides a toner image carrier with a toner image. A transfer roller disposed inside the toner image carrier permits transfer of the toner image to the transfer belt by orthogonal rotation as compared to the rotational direction of the transfer belt. The transferred image is displayed, then erased by a cleaning blade.

Abstract: A toner printing machine includes an image forming device forming a toner image on a workpiece, and a heating member from which a heat energy is supplied to the toner image to be fixed to the workpiece, wherein the heating energy is supplied to the toner image while preventing a contact heat energy transmission between the heating member and the toner image.

Abstract: In an image forming apparatus of transverse transfer type, toner images, carried by a toner-image carrying member extended by a plurality of rollers in a direction perpendicular to a direction of feed of printing paper, are transferred by a transfer opposed roller to the printing paper in a direction perpendicular to the direction of feed of the printing paper to be fixed. Among the rollers extending the toner image-carrying member, at least one of those rollers except for the transfer opposed roller, which comes closest to the transfer opposed roller at starting and terminal ends of a longest path of movement of the transfer opposed roller, respectively, is provided at a position spaced from a transfer surface of the printing paper, to which the toner images are transferred, by a distance larger than a diameter of the transfer opposed roller.
