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： An optical writing device includes a dichroic mirror and a deflection beam splitter. The dichroic mirror causes a light beam to pass therethrough or reflect depending on the wavelengths of the light beam. The deflection beam splitter causes a light beam to pass therethrough or reflect depending on a direction from which the light beam is received.

摘要： An image forming apparatus includes a plurality of image carriers and an optical writing device including light sources that emit light beams of different wavelengths, a deflector that deflects the light beams emitted from the light sources and synthesized on an identical axis in a sub-scanning direction, a first beam separator, a second beam separator, a first imaging device, and a second imaging device. The first beam separator and the second beam separator are located between the first imaging device and the second imaging device and transmit or reflect the light beams according to travel directions or wavelengths thereof. One of the targets is scanned with the light beam transmitted through the second beam separator. Another target is scanned with the light beam reflected by the second and first beam separators. The first and second imaging devices narrow the beams in the main scanning direction and the sub-scanning direction, respectively.
