发明名称 ELECTROPHOTOGRAPHIC SENSITIVE BODY
摘要 PURPOSE:To enhance the sensitivity of a photosensitive body by using a specified hydrazone compound as an electrostatic charge transfer material to be used for a photosensitive body composed essentially of an organic pigment. CONSTITUTION:In the case of the functionally separated multilayer photosensitive body, a charge generating pigment is vapor deposited on a conductive substrate or dispersed or mutually dissolved into a resin and applied to the conductive substrate, and on this layer the charge transfer layer containing the hydrazone compound represented by the formula shown on the right in which each of Ar1 and Ar2 is phenyl optionally substituted by halogen, alkyl, alkoxy, or nitro, and each of R1 and R2 is H, nitro, alkyl, alkoxy, phenyl (optionally substituted by halogen, alkyl, alkoxy, or nitro), benzyl, a group having an indole ring, N-carbazolyl, fluorenoyl, or triphenylanilyl. In this case, this hydrazone compound is used in an amount of 40-150wt% of the resin. When the charge generating pigment is dispersed into the charge transfer medium, this pigment is dispersed or mutually dissolved into the binder resin in an amount of 50-300wt% of the binder resin, and the hydrazone compound is dispersed or mutually dissolved in the binder resin in an amount of 40-150wt% of the resin. The charge generating pigment is added in an amount of 5-100wt% of the binder resin in the case of functionally separated type, thus enhancing the photosensitivity.
