PURPOSE:To obtain a resin compsn. for toner excellent in low temp. fixing property, offset resistance and blocking resistance by compounding a specified partial ester compd. of polyglycerine into a specified vinyl copolymer resin and further compounding a specified amt. of polyolefin wax thereinto. CONSTITUTION:A vinyl copolymer having 20,000 - 400,000 weight average mol.wt. is used as a binder resin, into which partial ester compd. of polyglycerine with org. carboxylic acid of >=10 carbon number is compounded. Further, 1 - 10pts.wt. of polyolefin wax is compounded to 100pts.wt. of the vinyl polymer. Thus, the obtd. resin compsn. is excellent in low temp. fixing property, offset resistance and blocking resistance. |
