(57) [Abstract] [Purpose] Color toner for electrostatic image development, which has excellent releasability, low-temperature fixability, offset resistance, and pulverizability, and a fixed image on which the surface of a transfer body can be written with a writing instrument using the same. There is provided an image forming method for forming a. In a color toner for developing an electrostatic charge image containing a colorant and a binder resin, the binder resin comprises a first polyester resin and a second polyester resin in a weight ratio of 70: 30-3. The first polyester resin has a storage elastic modulus of 1.0 to 5 × 10 4 Pa, a tan δ of 1.0 to 10 and a THF insoluble content of 10% by weight. And the second polyester resin has a storage elastic modulus of 5.0 × 10 −2 to 5.0 × 10 3 Pa and ta nδ is 2.0 to 500. When developing and fixing with this color toner for electrostatic image development, the transfer amount of the release agent to the transfer body is 2.0 × 10 −6 to 2.0 × 10 −5 g / cm 3. Apply the release agent to the heating roller so that it becomes 2 . |
