Document Type and Number:
WIPO Patent Application WO/1984/004825
Kind Code:
A1
Abstract:
An electrophotographic sensitized material capable of providing a toner-carrying surface being free from scumming and having high sensitivity, which mainly comprises polyvinylcarbazole or its derivative and a sensitizing dye represented by the general formula (I), (wherein Y represents S or formula (II), Y' represents S or formula (III), (wherein R2, R3, R2, and R3 each represents an alkyl group, with R2 and R3, or R2, or R3, optionally forming a ring), Z and Z' each represents halogen, nitro, cyano or alkyl-sulfonyl, R1 and R1 each represents a substituted or unsubstituted alkyl group, A is selected from -CH=CH-CH=, formula (IV) or (V), (wherein D represents halogen) or formula (VI), (wherein R4 and R5 each represents a substituted or unsubstituted alkyl or phenyl group), n1 and n2 each represents 0 or a natural number, with n1 + n2 > 2, and X represents an anion). An electrophotographic sensitized body comprises a support member having provided on one side thereof a conductive layer and the above-described sensitized material in sequence.
