Abstract:
A method for forming an image with at least one xerography unit of a plurality of xerography units in an image formation apparatus, comprising:charging a surface of an electrostatic latent image holding member; forming the electrostatic latent image on the charged surface of the image holding member; developing the electrostatic latent image to form a toner image using a developer containing a toner and a carrier on a developer holding member in a developing apparatus; and transferring the toner image onto an image member wherein the developing apparatus further includes a step of replenishing a replenisher toner into the developing apparatus by a replenishing system, and a step of discharging the developer from the developing apparatus to recover an excess portion of the developer by a discharging system, the replenisher toner containing a replenishing toner and a replenishing carrier, said carrier is in a range of 5 to 40% by weight thereof and having a coating on a core, said coating containing a resin and a conductive material, and said resin being composed of at least a monomer containing a carboxyl group, a monomer containing fluorine, an alkyl methacrylate monomer having a branch with 3 to 10 carbon atoms, and at least one of an alkyl methacrylate monomer containing a linear alkyl group with 1 to 3 carbon atoms and an alkyl acrylate monomer containing a linear alkyl group with 1 to 3 carbon atoms.
