PURPOSE:To improve moisture resistance by coating photoconductive particles with a polyparaxylene resin. CONSTITUTION:The surfaces of photoconductive particles are coated with a polyparaxylene resin of 0.01-10mu thicknesses, more particularly, 0.05-3mu, and these are dispersed in a binder resin to prepare a photoconductive layer. Di- paraxylene 4 is put in an evaporating port 3 placed in a quartz glass tube 1, and is heated in an evaporating furnace 2. The inside of the quartz glass is evacuated in the direction of an arrow 5 with a vacuum pump. The di-paraxylene is decomposed by heating in a decomposition furnace 6 to paraxylene radicals. The paraxylene radicals move into a polmn. chamber 7, which is held cooled, and caused interfacial polymn. on the surfaces of the photoconductive particles 9 falling from a vibrator 8, whereby the coated photoconductive particles 11 are obtd. in a vessel 10. Sufficient potential is obtainable with this photoreceptor in a highly moist atmosphere as well. |
