    Abstract: A polycarbonate copolymer, a coating liquid and an electrophotographic photosensitive body are provided. The polycarbonate copolymer has good abrasion resistance and stable solubility in an organic solvent. The copolymer comprises a repeating unit A of formula (1); a repeating unit B of formula (2); and a repeating unit C of formula (3), in which: the polycarbonate copolymer has a presence ratio represented byAr1/(Ar1+Ar2+Ar3) of from 50 to 65 mol %, a presence ratio represented byAr2/(Ar1+Ar2+Ar3) of from 25 to 45 mol %, and a presence ratio represented byAr3/(Ar1+Ar2+Ar3) of from 3 to 25 mol %: Ar1, Ar2, and Ar3 are each independently a divalent aromatic group, and X1 and X2 are each independently a single bond or —NH—, provided that Ar1 and Ar2 are not identical to each other. In the copolymer the repeating units B are not directly bonded to each other.
