PROBLEM TO BE SOLVED: To provide toner having sufficient chargeability and fixability while improving the dispersibility of a release agent. SOLUTION: In the toner comprising a plurality of binder resins, the toner contains a resin (A) having 5,000 to 40,000 weight average molecular weight, a crystalline resin (B) having the same coupling structure of the main chain as in the resin (A) and having 10,000 to 150,000 weight average molecular weight, and a resin (C) having the molecular weight larger than that of the resin (A) and having the same coupling structure of the main chain in the resin (B), and further contains a release agent having the weight average molecular weight smaller than that of the resin (A).
