Abstract:
(EN) This electrophotographic photosensitive body (1) is provided with a conductive substrate (2) and a photosensitive layer (3). The photosensitive layer (3) is a single layer-type photosensitive layer (3c) comprising a charge-generating agent, a hole transport agent, an electron transport agent, and a binder resin. The binder resin contains a polyarylate resin represented by general formula (1). In general formula (1), Q1, Q2, Q3, and Q4 each represent a methyl group or a hydrogen atom. r, s, t, and u each represent a number between 15 and 35 inclusive. X and y are divalent groups represented by chemical formula (2A), chemical formula (2B), chemical formula (2C), or chemical formula (2D). The hole transport agent is represented by general formulas (HTM1) to (HTM7). The scratch resistance depth of the photosensitive layer (3) is 0.50 µm or less. The Vickers hardness of the photosensitive layer (3) is 17.0 HV or less.
(FR) L'invention concerne un corps photosensible électrophotographique (1) comprenant un substrat conducteur (2) et une couche photosensible (3). La couche photosensible (3) est une couche photosensible de type couche unique (3c) et comprend un agent générateur de charge, un agent de transport de trou, un agent de transport d'électron et une résine liante. La résine liante comprend une résine de polyarylate représentée par la formule générale (1). Dans la formule générale (1), Q1, Q2, Q3 et Q4 représentent chacun un groupe méthyle ou un atome d'hydrogène. r, s, t et u représentent chacun un nombre compris entre 15 et 35 inclus. X et y sont des groupes divalents représentés par la formule chimique (2A), la formule chimique (2B), la formule chimique (2C), ou la formule chimique (2D). L'agent de transport de trou est représenté par les formules générales (HTM1) à (HTM7). La profondeur de résistance aux rayures de la couche photosensible (3) est inférieure ou égale à 0,50 µm. La dureté Vickers de la couche photosensible (3) est inférieure ou égale à 17,0 HV.
(JA) 本発明の電子写真感光体(1)は、導電性基体(2)と、感光層(3)とを備える。感光層(3)は、単層型感光層(3c)であり、電荷発生剤と、正孔輸送剤と、電子輸送剤と、バインダー樹脂とを含む。バインダー樹脂は、一般式(1)で表されるポリアリレート樹脂を含む。一般式(1)中、Q1、Q2、Q3及びQ4は、メチル基又は水素原子を表す。r、s、t及びuは、15以上35以下の数を表す。X及びY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である。正孔輸送剤は、一般式(HTM1)~(HTM7)で表される。感光層(3)の引っ掻き耐性深さは、0.50μm以下である。感光層(3)のビッカース硬度は、17.0HV以上である。
