ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER, ELECTROSTATIC CHARGE IMAGE DEVELOPING AGENT AND IMAGE FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner which allows high picture quality and has a sharp particle distribution, an electrostatic charge image developing agent using the toner and an image forming method.

SOLUTION: This electrostatic charge image developing toner is constituted in such a manner that the proportion (A) of metal atom which can take a valence number of bivalence or more and the proportion (B) of alkali metal atom which has the valence number of monovalence among the total metal atoms in the surface of the toner have a relation: 0.23≤A/(A+B)≤0.98, in an electrophotographic toner manufactured by using crystalline resin which has at least one or more melting point. Further, this electrostatic charge image developing agent contains the toner and carriers and this image forming method enables the formation of a toner picture by using the electrostatic charge image developing agent.
