ABSTRACT:
The invention is to provide polyhydroxyalkanoate of a novel structure enabling application to wider fields, and a producing method therefor. The invention also provides a biodegradable charge control agent having excellent charging characteristics, excellent dispersibility in the toner resin and improved spent property. The polyhydroxyalkanoate of the present invention is featured by including, in the polymer molecule, a units represented by the general formulas (1) and (2) and at least one of the units represented by the general formulas (3) to (6).
