| abstract | An electrophotographic photoreceptor (1; 11; 21; 31; 51; 71) comprising: a conductive substrate (101); a bottom layer (104) placed superimposed on the conductive substrate (101); a photosensitive layer placed superimposed on the lower layer (104) and comprising: a load generating layer (102) placed superimposed on the lower layer (104); and a load transport layer (103) placed superimposed on the load generation layer (102), in which, when the load generation layer (102) is irradiated with light having a maximum reflectivity for the layer of load generation (102) in a range between 360 nm and 740 nm after forming the lower layer (104) and the load generation layer (102) superimposed on the conductive substrate (101), the load generation layer (102) has a reflectivity of between 15 and 21%, in which the charge generation layer (102) contains a disazo pigment represented by the following formula (I): (See formula) in which A and B represent groups Remaining couplers represented by the following formulas (II) to (vIII): (See formulas) in which X 1 represents -OH, -NHCOCH3, and -NHSO2CH3, Y 1 represents -CON (R 2) (R 3), - CONHN = C (R 6) (R 7), -CONHN (R 8) (R 9), -CONHCONH (R 12), a hydrogen atom, COOH, -COOCH3, COOC6H5 and a benzimidazole group, in the that R 2 and R 3 independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group and a substituted or unsubstituted heterocyclic group or in which R 2 and R 3 when taken together they can form a ring with the nitrogen atom to which they are attached, R 6 and R 7 independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted styryl group and a substituted or unsubstituted heterocyclic group, or in which R 6 and R 7 when taken together can form a ring with the nitrogen atom to which they are attached, R 8 and R 9 represent independently a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted styryl group ustituted and a substituted or unsubstituted heterocyclic group or in which R 8 and R 9 when taken together with the carbon atom to which they are attached can form a five-membered ring or a six-membered ring and optionally have a ring condensed aromatic, and R 12 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, and Z represents a remaining group that fuses with the benzene ring to form an aromatic structure polycyclic or a heterocyclic structure selected from the group consisting of a naphthalene ring, an anthracene ring, a carbazole ring, a benzocarbazole ring, a dibenzocarbazole ring, a dibenzofuran ring, a benzonaphthofuran ring and a dibenzothiophene ring , each of which may have at least one substituent; (See formula) in which R 4 represents a hydrogen atom, a substituted or unsubstituted alkyl group, and a substituted or unsubstituted aryl group; (See formula) in which R 5 represents a hydrogen atom, a substituted or unsubstituted alkyl group, and a substituted or unsubstituted aryl group; (See formula) in which Y represents a divalent aromatic hydrocarbon group or in which Y together with the N-atoms to which it is linked forms a heterocyclic group; (See formula) in which Y represents a divalent aromatic hydrocarbon or in which Y together with the N-atoms to which it is linked forms a heterocyclic group; (See formula) in which R 10 represents a hydrogen atom, an alkyl group, a carboxyl group, and a carboxy ester group and Ar 1 is a substituted or unsubstituted aromatic hydrocarbon group; and (See formula) in which R 11 represents a hydrogen atom, an alkyl group, a carboxyl group, and a carboxy ester and Ar 2 is a substituted or unsubstituted aromatic hydrocarbon group, and in which the electrophotographic photoreceptor (1 ; 11; 21; 31; 51; 71) satisfies the following relationship: 12 (V / mum) <_ electric field strength (V / D) <_ 35 (V / mum), in which D (mum) represents a thickness of the charge transport layer (103) of the electrophotographic photoreceptor (1; 11; 21; 31; 51; 71) and V (V) represents an absolute potential of the surface of the electrophotographic photoreceptor (1; 11; 21; 31; 51; 71) due to the load. |
