FULL COLOR TONER KIT FOR ELECTROSTATIC IMAGE DEVELOPMENT, DEVELOPER, IMAGE FORMING DEVICE, AND PROCESS CARTRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a toner kit formed of full color toner where there is no turbidity of color obviously, electrification amount hardly varies even when the environment (temperature and humidity) changes, the stability of the image concentration is high, scumming does not occur, and a stable image can be formed in forming an electrophotographic image of full color. Ž

SOLUTION: This full color toner kit for electrostatic image development is formed of a color toner used together with black toner containing at least carbon black as a coloring agent. The volume resistivity of the black toner is 5.0×1010to 3.0×1011Ωcm. Each color toner contains conductive inorganic compound with a powder electric resistance (volume resistivity) of 50 Ωcm or lower, and the volume resistivity is 5.0×1010to 3.2×1011Ωcm. Ž
