A charge control agent containing a barium salt of a sulfoisophthalic acid compound and optionally a metal salt of a salicylic acid compound. A toner for developing an electrostatic latent image comprising such a charge control agent, a binder resin and a colorant.
摘要:
A toner for developing electrostatic latent images, including a colorant, a releasing agent and a binder resin, wherein the binder resin comprises a first, crystalline polyester resin, and a second, amorphous polyester resin having a softening point higher than that of the first polyester resin and being incompatible with the first polyester resin.
摘要:
A color toner composition including at least toner particles including at least a binder resin; a colorant and a release agent dispersed in the binder resin; and a titania as an external additive, wherein the colorant has an average dispersion particle diameter not greater than 0.5 μm; the release agent and the binder resin are insoluble to each other; the toner particles satisfy the relationship: 0.05≦Dw/D4≦0.4, wherein Dw represents an average dispersion particle diameter of the release agent and D4 represents a weight-average particle diameter of the toner particles; and the titania has a segregation rate of from 0.5 to 5%.

摘要:
An image removing method including bringing an outermost layer of a removing member into contact with an image fixed on an image support without applying a liquid to the image while heating the image and the outermost layer; and separating the removing member from the image support to remove the image from the image support, wherein the removing member includes a substrate and the outermost layer which is located overlying the substrate and which includes a thermoplastic resin, and wherein the image includes a removing agent which can decrease adhesion force of the image to the image support when heated.

摘要:
A toner prepared by a method of dissolving or dispersing toner constituents comprising a modified resin capable of reacting with an active hydrogen and a colorant which is a black metallic material to prepare a solution or a dispersion; and reacting the solution or dispersion with at least one of a crosslinking agent and an elongation agent in an aqueous medium including a resin particulate material.
