Patent ID: 7960083

Claim:
An image forming method, comprising steps of: charging a surface of a latent electrostatic image bearing member; exposing the surface, which is charged, of the latent electrostatic image bearing member to form a latent electrostatic image; developing the latent electrostatic image with a toner to form a visible image; transferring the visible image onto a recording medium; and fixing the image on the recording medium, wherein the toner comprises at least a binder resin and a colorant, and the binder resin comprises a polyester resin (A) and a polyester resin (B) which has a softening point 10° C. or more higher than that of the polyester resin (A), the polyester resin (A) is a (meth)acrylic acid-modified rosin derived resin having a polyester unit obtained by polycondensation of an alcohol component and a carboxylic acid component, the alcohol component containing 65 mol % or more of 1,2-propanediol in a dihydric alcohol component, and the carboxylic acid component containing a (meth)acrylic acid-modified rosin, and the polyester resin (B) is a purified rosin derived resin having a polyester unit obtained by polycondensation of an alcohol component and a carboxylic acid component, the alcohol component containing a total of 70 mol % or more of 1,2-propanediol and 1,3-propanediol in a dihydric alcohol component, and the carboxylic acid component containing a purified rosin.
