摘要： An image forming apparatus includes an image forming unit, a paper loading base on which manual-feed paper is loaded, a manual-feed paper conveying unit, and a dustproof cover which covers the paper loading base being in the overhang state. The paper loading base has a lower end rotatably supported on one outer surface portion of the device main body, and is opened from an upper end thereof and disposed at a predetermined oblique angle or in a horizontal overhang state such that an overhang side becomes an upper side in an oblique direction. The manual-feed paper conveying unit is conveys the manual-feed paper on the paper loading base onto a paper conveyance path one by one. The dustproof cover includes a base which engages with the paper loading base, and an opening-and-closing cover which is rotatably connected to the base and is opened upwardly on the overhang side.

摘要： A sheet feeder attracts an uppermost sheet of a sheet stack of a plurality of stacked sheets, and feeds the sheet in a sheet feeding direction. The sheet feeder includes an endless belt, a charging device, and a control device. The endless belt is made of a dielectric material, passes over upstream and downstream rollers, and is disposed above the sheet stack to face the sheet stack. The charging device applies an alternating voltage to an outer circumferential surface of the endless belt to form thereon alternating charge patterns. The control device separately controls the respective rotation states of the upstream and downstream rollers to make a sheet contact surface of the endless belt go slack in sheet attraction and make the sheet contact surface of the endless belt taut with tension into a substantially flat surface in sheet conveyance.

摘要： An inkjet recording apparatus provides an improved printing speed and improved convenience of use. A recording head discharges droplets of a recording liquid onto a paper so as to form an image on the paper. A belt conveyance mechanism has a belt onto which the paper is electrostatically attached. The paper attached onto the belt is conveyed in a direction perpendicular to a carding direction of the paper.
