Patent ID: 7873304

Claim:
An image forming apparatus comprising: a latent electrostatic image bearing member; a charging unit configured to charge a surface of the latent electrostatic image bearing member; an exposing unit configured to expose the charged surface of the latent electrostatic image bearing member to form a latent electrostatic image thereon; a developing unit configured to develop the latent electrostatic image with a toner to form a visualized image; a transferring unit configured to transfer the visualized image onto a recording medium; and a fixing unit configured to fix the visualized image to the recording medium, wherein the toner comprises a binder resin and a coloring agent, and the binder resin comprises a polyester resin obtained by condensation polymerization of an alcohol component and a carboxylic acid component containing a (meth)acrylic acid modified rosin, and the content of a low molecular weight component having a molecular weight of 500 or less in the polyester resin is 12% or less.
