摘要：
A polyhydroxyalkanoate containing in a molecule at least one unit represented by the chemical formula (1). The polyhydroxyalkanoate is a biodegradable plastic with enhanced melt-processability and exhibits excellent charging stability, high chargeability, and enhanced dispersibility when used as a charge control agent of a toner in an electrophotographic process. (R denotes -A1(-SO2R1)x. R1 is selected from OH, a halogen atom, ONa, OK, and OR1a. R1a and A1 are selected from a substituted or unsubstituted aliphatic hydrocarbon structure, a substituted or unsubstituted aromatic ring structure, and a substituted or unsubstituted heterocyclic structure. Further, m and x are integers selected from 1 to 8, and when two or more units exist, each of R, R1, R1a, A1, m, and x is defined as above independently for each of the units.)
