摘要： An ester polymer composed of solely the following repeating units (I): -(-W-X-O-CO-)- or both of the repeating units (I) and (II) and having a reduced viscosity [ eta sp/C] of 0.2-10.0 dl/g as measured with a solution thereof in methylene chloride at a concentration of 0.5 g/dl at 20 DEG C; a process for producing the ester polymer by the reaction of a dihydric phenol (III): HO-X-OH or a mixture of dihydric phenols (III) and (IV) with a carbonate-forming compound or a dibasic acid; and an electrophotographic photoreceptor comprising a photosensitive layer provided on a conductive support, wherein the ester polymer is used as a charge transport substance or a binder resin in the photosensitive layer. In said formulae, W represents -O- or a single bond; X represents a divalent group derived from a dihydric phenol containing a hydrazine structure; R and R represent each halogen, alkyl, cycloalkyl or aryl; m and n represents each an integer of 0 to 4; and Y represents a single bond, -O-, -S-, -SO-, -SO2-, -CR R -, 1,1-cycloalkylene or a alpha , omega -alkylene.

摘要： A polycarbonate polymer wherein the repeating unit is a group represented by general formula (I) and the terminal group is a group represented by formulae (I), (II), (III), (IV) or (V). In formula (I) R?1 and R2¿ represent each halogen, alkyl, cycloalkyl or aryl; a and b represent each independently an integer of 0 to 4; x represents a single bond, -O-, -CO-, -S-, -SO-, -SO¿2?-, -CR?3R4¿-, 1,1-cycloalkylidene or α,φ-alkylene; in formulae (II), (III), (IV) and (V) R5 represents C¿1?-C30 perfluoroalkyl which may be substituted; Y represents -CH2-; n represents an integer of 0 to 6; Z represents -O-, -CO-, -OCO-, -S-, -SO-, -SO2- or -NHCO-; f represents 0 or 1; R?6¿ represents halogen, alkyl, cycloalkyl or aryl; and c and d represent each an integer provided that c + d « 5, c = 1 - 5 and d = 0 - 4. An electrophotographic photoreceptor containing the polycarbonate as one component of the photosensitive layer, which is free from the problem of clouding (gelation) of a coating fluid used for making the same, retains excellent mechanical strengths such as plate wear, and can maintain excellent electrophotographic characteristics, thus being practically excellent.
