PURPOSE:To reduce the potential rise (fall) and to improve the moisture resistance by using a mixture of acrylic resin with vinyl chloride-vinyl ether copolymer resin as a binder in the photoconductive layer. CONSTITUTION:A mixture of two kinds of resins is used as a binder in a photoconductive layer. The 1st resin is acrylic resin having 5-40 acid value, 15-70 deg.C glass transition temp. and >=10,000 average mol.wt., and the 2nd resin is vinyl chloride-vinyl ether copolymer resin having 2,000-20,000 average mol.wt. The amount of the 2nd resin is 1-50pts.wt. per 10pts.wt. of the 1st resin. |
