PROBLEM TO BE SOLVED: To provide a full color toner for oilless fixing which is free of the occurrence of a spent wax and filming even if the toner contains an ester wax, and which is excellent in durability and grindability, a fixing method, a toner package container, and an image forming apparatus. SOLUTION: The full color toner for two-component development contains a polyester resin, a colorant and a carnauba wax and a synthetic ester wax having a long chain branch structure expressed by general formula (1). The resin content of the toner contains 30 to 50% component of a weight average molecular weight≤10,000 with respect to the entire weight of a THF soluble content and contains 0.5 to 10% component of≤1,000. In rheology characteristics measured by a temperature sweep method at a frequency 1 Hz and strain 10%, the viscosity at 130 to 180°C ranges from 80 to 3,500 Pa s and tanδexpressed by a ratio of a loss modulus G" and a storage modulus G' ranges from 1.0 to 4.0. In the formula (1), R1 and R2 represent 14-30C alkyl groups or alkenyl groups and R3 and R4 represent 14-30C alkyl groups. COPYRIGHT: (C)2006,JPO&NCIPI |
