<p>PROBLEM TO BE SOLVED: To provide a developer carrier having excellent wear resistance, constituted so that the change of surface roughness may be small, preventing stain on its surface and capable of stably carrying and feeding developer in a two-component developing device using magnetic substance dispersion type resin particulate carrier, and to provide a developing method, a developing device and an image forming device capable of effectively preventing the deterioration of image quality caused by the excess electrification of developer in the two-component developing device and obtaining a stable image even in endurable use over a long term under every environment. SOLUTION: The developer carrier to carry two-component developer having the magnetic substance dispersion type carrier where magnetic substance is dispersed in binding resin for carrier and non-magnetic toner is constituted by providing a covering layer where conductive spherical particles are at least dispersed in binding resin for a covering layer on base substance. Then, the developing device has the developer carrier and the image forming device has the developing device.</p> |
