The invention is to provide a toner, a toner cartridge and a developing device using the same in that an excellent image without a defect on the image is obtained in a long period of time, and stable agitation and transportation can be conducted. In a toner cartridge containing a toner containing at least a binder resin, a colorant and wax, inside the toner cartridge, and a toner agitating and transporting member for supplying the toner under agitation and transportation, the toner contains the wax in an amount of from 3 to 10% by weight and has a mean particle diameter of from 3 to 10 &mgr;m, and the toner agitating and transporting member is arranged as rotatably inside the toner cartridge to form a distance of from 0.5 to 3.0 mm between the member and an inner wall of a main body of the toner cartridge.

Toner agitating and transporting member of a toner cartridge and developing device

A toner for electrostatic-image development which comprises toner particles comprising a colorant and a binder resin, the toner particles having a volume-average particle diameter of from 3 to 9 .mu.m and a particle size distribution satisfying the following expressions (1) and (2):

Toner for electrostatic-image development, developer for electrostatic

The toner for full-color image formation of the invention comprises a binder resin and a colorant, wherein the toner has a volume-average particle diameter of from 3.0 to 9.0 .mu.m and satisfies relationship (1) between the volume-average particle diameter and a colorant content thereof:

Toner for full-color image formation, developer composition, and method

An electrically-conductive toner comprising toner mother grains and a lubricant which is at least one selected from the group consisting of an aliphatic acid, an aliphatic acid metal salt, an aliphatic alcohol, an aliphatic amide, an aliphatic bisamide, and an aliphatic acid ester, the lubricant being in the form of finely divided grains having such a diameter that at least 99% by number of the finely divided grains have a diameter of 3 .mu.m or less.
