Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, COATING LIQUID FOR ELECTROPHOTOGRAPHIC PHOTORECEPTOR LAYER FORMATION, COMPOUND, ELECTROPHOTOGRAPHIC PHOTORECEPTOR CARTRIDGE, AND IMAGE FORMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/127784
Kind Code:
A1
Abstract:
As a compound having sufficient solubility in an organic solvent, a novel compound, according to the present invention, having an electron transporting property is proposed, the compound being represented by formula (1). In addition, as a novel electrophotographic photoreceptor configured such that even if a protective layer contains an electron-transporting compound, a protective layer having a uniform composition can be formed without the electron-transporting compound agglomerating or precipitating, and such that favorable electrical characteristics and particularly a residual potential characteristic can be achieved, an electrophotographic photoreceptor is proposed comprising, on a conductive support, at least a photosensitive layer and a protective layer in that order. The protective layer contains a polymer of the electron-transporting compound represented by formula (1). (In formula (1), L1 and L2 each independently represent a divalent group. Ar1 and Ar2 each independently represent a C6-30 divalent aromatic group or a C3-30 divalent heteroaromatic group. E1 and E2 each independently represent a divalent group. P1 and P2 each independently represent a chain-polymerizable functional group. R1 and R2 each independently represent an alkyl group optionally having a substituent, an alkoxy group optionally having a substituent, an aryloxy group optionally having a substituent, a hetero-aryloxy group optionally having a substituent, an alkoxycarbonyl group optionally having a substituent, a dialkylamino group optionally having a substituent, a diarylamino group optionally having a substituent, an arylalkyl amino group optionally having substituent, an acyl group optionally having a substituent, a haloalkyl group optionally having a substituent, an alkylthio group optionally having a substituent, an arylthio group optionally having substituent, a silyl group optionally having a substituent, a siloxy group optionally having a substituent, a halogen atom, a cyano group, an aromatic hydrocarbon group optionally having a substituent, or an aromatic heterocyclic group optionally having a substituent. a1, a2, b1, b2, c1, and c2 each independently represent an integer of 1 or greater. d1 and d2 each independently represent an integer from 0 to 6. d1 + d2 is 1 or greater. n1 and n2 each independently represent an integer of 0 or greater.)
