in transparency and was free from cracks a coating solution for electric charge conveying layer was prepared by using 100 parts by weight of polyallylate u 100 of unitika 100 parts by weight of 4 n n diethylamino benzaldehyde n n diphenyl hydrazine and 900 parts by weight of methylene chloride ch 2 cl 2 and this coating solution was applied on an aluminum tube of 78 mm in outside diameter by 340 mm in length and was heated for 30 minutes at 100 u00b0 c and an electric charge conveying layer of film thickness of 20 u03bcm was formed on this electric charge conveying layer was applied a coating solution for electric charge generating layer comprising 80 parts by weight of 2 7 dibromoansanthrone ici 20 parts by weight of metal free phthalocyanine basf 50 parts by weight of polyvinyl acetate y5 n of nippon gosei kagaku and 2000 parts by weight of diacetone alcohol and it was dried in the same condition as above and an electric charge generating layer of film thickness of 0 5 u03bcm was formed mixing 57 4 parts by weight of 0 02n hydrochloric acid and 36 parts by weight of isopropyl alcohol the obtained mixed solution was stirred while keeping.
