Toners for developing electrostatic latent images, developers for electrostatic latent images and methods for forming images

摘要

A toner for developing an electrostatic latent image includes at least coloring particles containing a colorant and a binder resin. The volume average particle size of the coloring particle is 1.0 to 5.0 mu m. The toner is further characterized in that (1) the relationship between the quantity of the electric charge and the particle size is adjusted appropriately, (2) the particle size distribution is adjusted appropriately and/or (3) an external additive comprising at least an ultra microparticle and a super-ultra microparticle may be added, the rate of coating on the coloring particle being adjusted appropriately. A method for forming an image includes (1) a developing step in which a toner layer is formed on the surface of a developer support arranged opposed to a latent image support and an electrostatic latent image on the latent image support is developed with the toner layer to obtain a toner image and (2) a transfer step in which the toner image formed is transferred to a transfer material. The Rz of at least an image receiving region of the transfer material provided for the transfer step is preferably 10 mu m or less.
