Abstract

The invention relates to a carrier core material and a manufacturing method of the carrier core material, a carrier and an electrostatic charge image developing agent. The carrier core material comprises the following main components and auxiliary components, wherein the main components comprise 72.0-72.5 mol% of Fe2O3, 8.0-8.5mol% of Mn3O4, and 19.0-19.5mol% of MgO; the additive amounts of the auxiliary components are as follows (by weight percent of the main components): 0.04-0.06wt% of V2O5, 0.10-0.12 wt% of CaO, and 0.01-0.03wt% of SiO2. A carrier particle containing the carrier core provided by the invention has good mobility, the electric quantity of a color matching agent is stable, a fracture phenomenon and fragments are not generated for long time use, the developing agent is used for an image forming device and can control the degradation of image quality.

Description

technical field [0001] The invention relates to the field of manufacturing an electrostatic charge image developer, in particular to a carrier core material for an electrostatic charge image developer and a manufacturing method thereof, a carrier containing the carrier core material, and an electrostatic charge containing the carrier core material. image developer. Background technique [0002] In recent years, with the automation of office equipment and the popularization of image forming devices such as high-speed printers, copiers, and multi-function machines that use electrostatic charge image forming methods, the market has demanded high image quality, long life of developers, and devices. The requirements for high speed and miniaturization are also getting higher and higher. As the image-forming developer corresponding to the image forming apparatus, a one-component developer composed of only toner or a two-component developer composed of carrier and toner can be used...
