  • Publication number: 20120052430
    Abstract: An electrostatic image developing toner includes a core particle containing a binder resin and a coating layer on the core particle. The coating layer contains a resin having a crosslinked structure formed by using at least one of boric acid and derivatives thereof, and the resin having the crosslinked structure is obtained by polymerizing monomers in the presence of the core particle.

  • Publication number: 20110020030
    Abstract: An image forming method includes charging an image holding member; forming an electrostatic latent image on a surface of the image holding member; developing the electrostatic latent image formed on the surface of the image holding member with a toner or an electrostatic image developer to form a toner image; transferring the toner image formed on the surface of the image holding member onto a surface of a transfer-receiving material; fixing the toner image by pressurization without heating; feeding at least one photoreactive component to the toner or toner image; and irradiating the toner image with ultraviolet rays, wherein the toner satisfies the relationship of the following relational expression (1): TB(30)?100<TA(30)??(1) wherein TB (30) and TA (30) are defined in the specification.
