Abstract: There is provided a secondary transfer device for secondary-transferring a toner image primary-transferred on an outer peripheral surface of an endless annular intermediate transfer belt to a sheet at a predetermined secondary transfer position, the intermediate transfer belt having a predetermined width and being wound around a plurality of rollers and rotating, the secondary transfer device including: a pressure-releasing mechanism that displaces a secondary transfer roller to a pressing position and a separation position; a first drive that drives the pressure-releasing mechanism; a high-speed depressurization mechanism that temporarily depressurizes a nip pressure, at which the secondary transfer roller at the pressing position interposes and presses the intermediate transfer belt in a gap with respect to the opposite roller, when a leading end and a tailing end of a sheet pass between the secondary transfer roller and the intermediate transfer belt; and a second drive that drives the high-speed depressur

Abstract: An image forming apparatus includes a cleaning unit that includes a cleaning blade, a coating roller that comes in contact with an image carrier on an upstream side, in a conveyance direction, of the image carrier than the cleaning blade and coats toner onto the image carrier, and a plate member that comes in contact with the coating roller and coats toner onto the coating roller, and controls a contact force changer that changes a contact force of the plate member relative to the coating roller and/or a contact force of the coating roller relative to the image carrier, correspondingly to a change of an index with regard to the contact force of the coating roller.

Abstract: A built-in monitor apparatus such as an electronic game machine and etc., which is adapted to allow a built-in monitor unit having a rectangular picture screen to rotate in a 90-degree arc. This built-in monitor apparatus comprises; a monitor unit comprising a cathode-ray tube; a base unit comprising a frame for rotatably supporting the monitor unit, and a stretchable damper biased to be moved forward, each end of the damper being pivotally connected to a portion between the frame and said casing; a guide roller mounted on the frame and adapted to slide along a guide rail provided within the casing; and a locking means for restraining the movement of the frame.
