ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER, METHOD OF PRODUCING THE SAME, ELECTROSTATIC CHARGE IMAGE DEVELOPING DEVELOPER, AND IMAGE FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing black toner excellent in blackness, electrostatic chargeability and safety, a method for producing the toner, and a developer and an image forming method using the developer. SOLUTION: In the electrostatic charge image developing black toner obtained by dispersing a colorant in a resin, 6-50 wt.% fine particles of a black metallic compound having 40-500 nm median particle diameter and <=30 emu/g magnetic force are contained as the colorant in the toner. The water content of the toner is <=0.5 wt.% and the dielectric loss of the toner is <=50. The manufacturing method of the toner, the developer and the image forming method using the toner are also provided.
