TONER FOR ELECTROSTATIC CHARGE IMAGE DEVELOPMENT

摘要

This invention provides a toner for an electrostatic charge image development, characterized by comprising a novel carbon black having a number average particle diameter of Feret's diameters of 5 to 300 nm and containing not less than 5%, on the basis of number of particles, of primary particles. The toner can prevent a change in Q/M caused by adherence onto a carrier or a sleeve, is free from fogging, toner scattering and the like, and can maintain stable performance for a long period of time.
