Abstract
PURPOSE:To prepare an electrophotographic photoconductive layer capable of exhibiting constant potential characteristics independent of the length of the storage time of a coating liquid, by coating a mixture obtained by mixing photoconductor particles and a binder resin under a reduced pressure to form the photoconductive layer. CONSTITUTION:A vessel 4 containing photoconductor particles 5, such as ZnO or Se is arranged in an evacuable vessel 3, and the inside of the vessel 3 is evacuated to <=100mm.Hg by driving a vaccum pump 7. A solution 5 containing a binder resin, such as polyethylene or polyester is introduced by opening a valve 8 so as to adjust a proportion to 0.5-50pts.wt. binder resin per 100pts.wt. photo-conductor, and mixed with a stirrer 6 to give a coating liquid. This is coated on a substrate to 5-1,000mum thickness and dried to form a photoconductive layer, thus preventing the binder resin from intruding into the porous holes of the photoconductor particle surfaces, and covering the particles 5 by forming homegeneous coating films, and from making unstable the potential characteristics due to locally left air, solvent vapor, or the like.
