    • PURPOSE:To obtain the photosensitive body having a high sensitivity and less residual potential by adding sodium acetate to a charge generating layer contg. an azo compd. CONSTITUTION:Aluminum, copper, etc., are used as a base 1 and the fine particles of he azo compd. and the sodium acetate are dispersed into a soln. dissolved with a binder. This soln. is applied on the base 1 and is dried, by which the charge generating layer 2 is obtd. A soln. dissolved with a charge transfer material and a binder is applied thereon and is dried, by which a charge transfer layer 3 is produced. Polystyrene, polacrylamide, etc., are used as the binder. The thickness of the layer 2 is preferably 0.01 to 5mum and the thickness of the layer 3 is preferably 3 to 50mum. The ratio of the azo compd. in the layer 2 is specified to >=30wt.T and the amt. of the sodium acetate to be used is specified to 5 to 1000 pts. wt. per 10000 pts. wt. azo compd. The charge transfer material is incorporated at 10 to 95wt.% into the layer 3. Since the sodium acetate is added into the charge generating layer, the sensitivity is greatly improved.
