<p>PROBLEM TO BE SOLVED: To provide the electrostatic charge image developing toner superior in fluidity and chargeability and capable of preventing occurrences of smear and offset and filming at the time of copying. SOLUTION: This electrostatic charge image developing toner is composed of at least a binder resin, a polyethylene wax, a polypropylene wax, and a colorant, and the binder resin is a styrenic copolymer containing methyl methacrylate in an amount of 5-30 weight% of the total monomer components in terms of the monomer components, and this styrenic copolymer has a number average molecular weight 2,000-10,000 and a ratio of a weight average molecular weight to a number average molecular weight is in the range of 20-90.</p> |
