A sheet post-processing apparatus includes a plurality of bin trays arranged in multiple levels with predetermined intervals; stacking device supported in said apparatus so as to be moved in an arrangement direction of said plurality of bins; discharging device for discharging a sheet; and transferring device for transferring the sheet to said stacking device from said bin tray having completed sheet reception.

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.

A sheet post-processing apparatus includes at least one sheet receiving bin for receiving sheets. A sheet discharger discharges sheets into the sheet receiving bins and a post-processor post-processes the sheets stored in the sheet receiving bins. A support supports the sheet discharger, for movement between a first location at a discharging location for discharging the sheets into the sheet receiving bins and a second location at a retracted position away from the first location. A moving device moves the sheet discharging means from the first location to the second location when relative movement is imparted between the sheets and the post-processor so that the post-processor is activated at a predetermined location along the edges of the sheets in the sheet receiving bins.

A sheet processing apparatus includes a first sheet feeder for feeding a first sheet; a second sheet feeder for feeding a second sheet for discrimination; a sheet sticking device for sticking the second sheet fed from said second sheet feeder on the first sheet in the first sheet feeder such that a part of the second sheet is partly extended out of the first sheet.
