Title (EN) ELECTROPHOTOGRAPHIC PHOTORECEPTOR
(FR) PHOTORÉCEPTEUR ÉLECTROPHOTOGRAPHIQUE
(JA) 電子写真感光体
Abstract:
(EN) An electrographic photoreceptor (1), provided with an electroconductive base (2) and a photosensitive layer (3). The photosensitive layer is provided with a charge generation layer (3a) and a charge transportation layer (3b). The charge generation layer contains a charge-generating agent. The charge transportation layer contains a hole transportation agent, a binder resin, and a phthalocyanine-type pigment. The binder resin contains a polyarylate resin. The polyarylate resin is represented by general formula (1). The amount of the phthalocyanine-type pigment contained is 0.01-1.00 mass parts, relative to 100 mass parts of the binder resin. In general formula (1), kt represents 2 or 3. X represents a divalent group represented by chemical formula (2A), chemical formula (2B), chemical formula (2C), or chemical formula (2D).
(FR) La présente invention se rapporte à un photorécepteur électrographique (1) qui est pourvu d'une base électroconductrice (2) et d'une couche photosensible (3). La couche photosensible est pourvue d'une couche de génération de charge (3a) et d'une couche de transport de charge (3b). La couche de génération de charge contient un agent de génération de charge. La couche de transport de charge contient un agent de transport de trous, une résine liante et un pigment de type phtalocyanine. La résine liante contient une résine polyarylate. La résine polyarylate est représentée par la formule générale (1). La quantité du pigment de type phthalocyanine contenue est de 0,01 à 1,00 parties en masse, par rapport à 100 parties en masse de la résine liante. Dans la formule générale (1), kt représente 2 ou 3. X représente un groupe divalent représenté par la formule chimique (2A), la formule chimique (2B), la formule chimique (2C), ou la formule chimique (2D).
(JA) 電子写真感光体(1)は、導電性基体(2)と、感光層(3)とを備える。感光層は、電荷発生層(3a)と、電荷輸送層(3b)とを備える。電荷発生層は、電荷発生剤を含む。電荷輸送層は、正孔輸送剤と、バインダー樹脂と、フタロシアニン系顔料とを含む。バインダー樹脂は、ポリアリレート樹脂を含む。ポリアリレート樹脂は、一般式(1)で表される。フタロシアニン系顔料の含有量は、バインダー樹脂100質量部に対して0.01質量部以上1.00質量部以下である。一般式(1)中、ktは2又は3を表す。Xは、化学式(2A)、化学式(2B)、化学式(2C)、又は化学式(2D)で表される二価の基を表す。
