Carrier for electrostatic charge development, developer for electrostatic charge development, developer cartridge for electrostatic charge development, process cartridge, and image formation device

摘要

PPROBLEM TO BE SOLVED: To provide a carrier for electrostatic charge development capable of preventing the occurrence of image defect even when forming an image having low density at high speed, to provide a developer for electrostatic charge development including the carrier for electrostatic charge development, a developer cartridge for electrostatic charge development by use of the developer for electrostatic charge development, a process cartridge, and an image forming apparatus. PSOLUTION: The carrier for electrostatic charge development has a core material constituted by dispersing magnetic particles into a resin and a covering layer covering the core material, and contains magnetoplumbite ferrite as the magnetic particle. The developer for electrostatic charge development containing the carrier for electrostatic charge development, a developer cartridge for electrostatic charge development, a process cartridge, and an image forming apparatus are also provided.
