Title:
NOVEL COMPOUNDS AND ELECTROPHOTOGRAPHIC PHOTORECEPTORS AND ELECTROPHOTOGRAPHIC APPARATUS MADE BY USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2005/003093
Kind Code:
A1
Abstract:
The invention provides compounds useful for electrophotographic photoreceptors and excellent in electron transport power; positive charging electrophotographic photoreceptors for highly sensitive copying machines and printers, which contain such novel organic materials in the photosensitive layer as the charge transport substance; and electrophotographic apparatus made by using the same. The above compounds are novel ones having structures represented by the general formula (I): (I) wherein R1, R2, R3 and R4 are each alkyl or the like; R5 and R6 are each aryl or the like; and Z is a structure represented by the general formula (F-A), (F-B), or (F-C): (F-A) (F-B) (F-C) (wherein R7 and R8 are each optionally substituted alkyl; m and n are each an integer of 0 to 2; and X is sulfur and oxygen).
