To provide an image forming apparatus, image forming method and process
cartridge, which are excellent in low-temperature fixation properties,
storage stability, durability and filming resistance, can reduce
generation of odor, and are capable of forming an extremely high quality
image. The apparatus includes: a latent electrostatic image bearing
member; a charging unit; an exposing unit; a developing unit; a
transferring unit; and a fixing unit; wherein the toner comprises a
binder resin and coloring agent, and the binder resin comprises a
polyester-based resin (A) and polyester-based resin (B) having a melting
point at least 10.degree. C. higher than that of the polyester-based
resin (A), and at least one of the polyester-based resins (A) and (B) is
a resin derived from a (meth)acrylic acid modified rosin and includes a
polyester unit obtained by condensation polymerization of an alcohol
component and a carboxylic acid component containing a (meth)acrylic acid
modified rosin.
