Claim:
An electrophotographic imaging member having an overcoat layer, the overcoat layer comprising a cured film formed from a composition comprising at least a hydroxyl group-containing polymer selected from the group consisting of a polyester polyol represented by formula (1): [—CH 2 —R a —CH 2 ] m —[—CO 2 —R b —CO 2 —] n —[—CH 2 —R c —CH 2 ] p —[—CO 2 —R d —CO 2 —] q (1) wherein Ra and Rc independently represent linear or branched alkyl groups having from 1 to about 20 carbon atoms and being derived from a polyol; Rb and Rd independently represent alkyl groups having from 1 to about 20 carbon atoms or aryl groups having from 6 to about 60 carbon atoms and being derived from a polycarboxylic acid, m, n, p, and q independently represent mole fractions of from 0 to 1 and n+m+p+q=1, an acrylated polyol represented by formula (2): [R t —CH 2 ] t —[—CH 2 —R a —CH 2 ] p —[—CH 2 O—R b —CH 2 O—] n —[—CH 2 —R c —CH 2 ] p —[—CH 2 O—R d —CH 2 O—] q (2) wherein R t represents CH 2 CR 1 CO 2 — where R 1 is an alkyl group of from 1 to about 20 carbon atoms or more and where t represents mole fractions of acrylated sites from 0 to 1; Ra and Rc independently represent linear alkyl or alkoxy groups or branched alkyl or alkoxy groups derived from a polyol, the alkyl or alkoxy groups having from 1 to about 20 carbon atoms; Rb and Rd independently represent alkyl or alkoxy groups, the alkyl or alkoxy groups having from 1 to about 20 carbon atoms; and m, n, p, and q independently represent mole fractions of from 0 to 1 and n+m+p+q=1, a polyether polyol represented by formula (3): —[—CH 2 —R a —CH 2 ] m —[—CH 2 O—R b —CH 2 O—] n —[—CH 2 —R c —CH 2 ] p —[—CH 2 O—R d —CH 2 O—] q (3) wherein Ra and Rc independently represent linear alkyl or alkoxy groups or branched alkyl or alkoxy groups derived from a polyol, the alkyl or alkoxy groups having from 1 to about 20 carbon atoms; Rb and Rd independently represent alkyl or alkoxy groups, the alkyl or alkoxy groups having from 1 to about 20 carbon atoms, or aryl groups having from 6 to about 60 carbon atoms; and m, n, p, and q represent mole fractions of from 0 to 1 and n+m+p+q=1, and mixtures thereof, a benzoguanamine compound represented by: wherein R is an alkyl group having from 1 to about 10 carbon atoms, or a mixture thereof, and a charge transport compound represented by: wherein Q represents a charge transport component, L represents a divalent linkage group, and n represents a number of from 1 to about 8.
