    摘要: A sheet separating and feeding unit incorporable in an image forming apparatus includes an image forming device, a sheet container, a sheet feeding unit including an endless, dielectric belt and an electric potential pattern forming unit, a belt supporting mechanism including a first supporting roller and a second supporting roller, and a moving unit. The first supporting roller rotates to rotatably move the second supporting roller between a sheet attracting position and a sheet feeding position so that the flat portion of the dielectric belt moves between the sheet contact position and the sheet pick-up position.

    摘要: In a sheet separator of a sheet supplier, a friction separator and an electrostatic separator separate an uppermost sheet from other sheets of a plurality of sheets loaded on a sheet tray by a friction force and an attraction force generated by a non-uniform electric field, respectively. A conveyance member is provided downstream from the friction separator and the electrostatic separator in a sheet conveyance direction to feed the uppermost sheet separated by at least one of the friction separator and the electrostatic separator in the sheet conveyance direction. The friction separator and the electrostatic separator are arranged in such a manner that planes of projection of the friction separator and the electrostatic separator overlap or coincide in a direction perpendicular to the sheet conveyance direction in which the conveyance member feeds the uppermost sheet.

    摘要: A sheet feeding device including a belt including a dielectric material seamlessly wound about rollers and disposed opposite a top surface of a stack of multiple sheets placed on a sheet storage stand to attract a sheet from the stack of multiple sheets and convey the sheet, and a charger to form a predetermined charge pattern on a surface of the belt. A shaft of one of the rollers provided downstream from the other roller in a direction of sheet feed serves as a pivot of the belt about which the belt swings, and the belt swings around the pivot such that the surface of the belt facing the top surface of the stack of multiple sheets and a surface of the sheet storage stand facing the surface of the belt are substantially parallel to each other.

    摘要: A method for feeding sheet materials is disclosed, which is implemented by forwarding a plurality of sheet materials loaded on a loading plate with a rotating feeding roller toward a separation unit, for the leading edge of the sheet materials to be collided with a tapered face of taper member, and subsequently separating the uppermost of the loaded sheet materials through frictional force from the feeding roller after climbing over the taper member to be forwarded further to an image forming unit by way of a nip forming portion, while other underlying sheet materials are halted by the taper member owning to smaller frictional forces there between, thereby obviating the multiple feeding. In addition, the conditions suitable for sheet feeding can be satisfied for various sheet materials different in size and thickness by adjusting the distance between the point of contact of the uppermost sheet material with the feeding roller and that of nip formation, such that modulus values are equated to various sheet materials. As a result, considerably high sheet separation qualities are obtained obviating undue non-feeding or multiple feeding, and various kinds of sheet materials different in size, thickness and coefficient of friction, can be forwarded sheet by sheet securely to image forming unit, thereby achieving satisfactory image formation by means of image forming apparatuses incorporating the sheet feeding apparatuses disclosed herein.
