HYBRID MATERIAL FOR MAGNET, MOLDED MAGNET AND METHOD OF MANUFACTURING IT, DEVELOPMENT MAGNET ROLLER, DEVELOPMENT UNIT, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a novel hybrid material for a resin-bound magnet formed by compression molding which improves orientation in molding under a magnetic field and makes the magnet highly magnetized even by low-pressure compression molding.

SOLUTION: The hybrid material for the magnet whose main components are magnetic powder and fine particles of a thermoplastic resin further contains at least either a pigment or an electrification control agent.
