COMPACT OPTICAL PRINTER WITH PLANAR PHOTORECEPTOR

摘要

An optical printer includes a housing in which a photoreceptor including a transparent substrate, a transparent electrode layer and a photosensitive layer composed of a-Si which are formed on the substrate is housed. A main surface of photoreceptor is moved in a first direction parallel therewith. The charging of the photoreceptor, the forming of an electrostatic latent image and the toner-developing are performed at approximately the same time and a toner image formed on the photoreceptor is transcribed onto a paper by a transcribing roller. The paper which is inserted from a first opening formed on the housing is fed in the first direction with respect to the transcribing roller through a first feeding path. A contact line sensor is arranged above the photoreceptor at a position in the vicinity of the transcribing roller. An original which is inserted from a second opening formed on the housing is fed to the line sensor in a second direction opposite to the first direction through a second feeding path. The first and second feeding paths include a common feeding path. In addition, a transcribed toner image is fixed on the paper by a fixing device.
