Abstract
The present invention aims to provide an electrophotographic photoreceptor excellent in abrasion resistance and electrical properties, which uses polymers excellent in surface-active functions such as fluororesin dispersibility and electrical properties, and relates to an electrophotographic photoreceptor which contains a polymer containing a repeating unit represented by the following Formula (A1), provided that the definitions of X1, X2, R11 to R16 in Formula (A1), and R21 in Formula (A2) are shown in the specification
Claims10
An electrophotographic photoreceptor comprising a polymer containing a repeating unit represented by the following Formula (A1):
- wherein in the formula (A1), X1 and X2 each independently represent a hydrocarbon group which may have a substituent, or a group represented by the following Formula (A2);
- R11 to R13, and R15 to R16 represent a hydrogen atom, or a hydrocarbon group which may have a substituent;
- R14 represents a hydrocarbon group which may have a substituent;
- Z represents a terminal group;
- and n represents an integer of 1 or more, and
- wherein in the Formula (A2), R21 represents a hydrogen atom, a hydrocarbon group which may have a substituent, or a heterocyclic group which may have a substituent.
