Abstract: An electrophotographic photosensitive member having a high sensitivity to long-wavelength light as emitted by a semiconductor laser and causing little change in potential change during repetitive use is formed by using as a charge-generating material a hydroxygallium phthalocyanine having a crystal form characterized by a strongest peak at a Bragg angle (2.theta..+-.0.2 deg.) of 28.1 deg. in a CuK.sub..alpha. characteristic X-ray diffraction pattern. The hydroxygallium phthalocyanine may preferably be produced through a process including treating a halogenated gallium phthalocyanine for conversion into a hydrous hydroxygallium phthalocyanine, freeze-drying the hydrous hydroxygallium phthalocyanine into a low-crystallinity hydroxygallium phthalocyanine, and milling the low-crystallinity hydroxygallium phthalocyanine.

The separator is formed of a plurality of separation portions each including a sheet supply roller rotated in a sheet feeding direction and a sheet return roller rotated in a direction opposite to the sheet feeding direction, each disposed along a width-wise direction of the sheet. A sheet supplying force of a central separation portion disposed substantially at a center of the sheet in the width-wise direction is selected to be greater than that of the other separation portions.

Abstract: The present invention provides an automatic original supplying apparatus which includes an original stacking plate on which originals can be rested, and an original conveyor for separating and supplying the original, one by one, and for conveying the separated original to a reading position. It operates in a flow reading mode in which a reader is fixed and the original is shifted with respect to the reader, a fix reading scan mode in which the original is fixed at the reading position and the reader is shifted with respect to the fixed original, and a count mode in which the number of originals is counted. The original conveying speed in the fix reading scan mode is faster than the original conveying speed in the flow reading mode, and, in the count mode, the original is conveyed under the flow reading mode.
