ELECTROSTATIC IMAGE DEVELOPING TONER, ELECTROPHOTOGRAPHIC CARTRIDGE PROVIDED WITH SAID TONER, AND IMAGE FORMING DEVICE
The present invention relates to an electrostatic image developing toner comprising a binder resin, a coloring agent, and a wax, wherein the toner further comprises a specific charge control resin, and the wax contains an ester wax.
1 . An electrostatic image developing toner comprising a binder resin, a coloring agent, and a wax, wherein the toner further comprises a charge control resin represented by the following formula (1), and the wax contains an ester wax:
wherein R 1 represents a hydrogen atom, a halogen atom, alkyl group, —COC p H 2p+1 (p is an integer of 1 to 20), aralkyl group, substituted or unsubstituted phenyl group, substituted or unsubstituted amino group, nitro group, an alicyclic group, —SO 3 H, —Si(CH 3 ) 3 , alkoxyl group, carboxyl group, sulfonamide group, cyano group, or acyl group; R 2 represents alkyl group, substituted or unsubstituted phenyl group, or substituted or unsubstituted aralkyl group; R 3 and R 4 each independently represent a hydrogen atom, alkyl group of 1 to 12 carbon atoms, substituted or unsubstituted phenyl group, or a heterocyclic group containing a nitrogen or an oxygen atom; R 5 to R 8 each independently represent a hydrogen atom, a halogen atom, alkyl group, aralkyl group, or substituted or unsubstituted amino group; (m+n) is an integer of 4 to 8; m is an integer of 1 or more; and n is an integer of 0 or more.
2 . The electrostatic image developing toner according to claim 1 , wherein the content of the ester wax in the wax is 50 weight % or more.
3 . The electrostatic image developing toner according to claim 1 , wherein the content of the charge control resin represented by the formula (1) in the toner is 0.1 weight % to 2.5 weight %.
4 . An electrophotographic cartridge comprising the electrostatic image developing toner of claim 1 .
5 . An image forming device comprising the electrostatic image developing toner of claim 1 .
