摘要： PROBLEM TO BE SOLVED: To reduce the deterioration of toner with the lapse of time, as compared with heretofore, while ensuring the sufficient amount of toner supply to a toner carrier in a configuration to perform development, by conveying only the toner in a two-component developer by the toner carrier to a development region. SOLUTION: Since a brush roller 403, formed with a brush on the surface, is used as a toner supply member, the bristles of the brush are interposed in the magnetic brush by the magnetic particles 11 in the two-component developer formed on the brush roller 403. The flocculation density of the magnetic brush can be thereby reduced, to make the magnetic brush softer and the mechanical stress, to which the toner 10 is subjected in the toner supply region A2 can be suppressed to be small.

摘要： PROBLEM TO BE SOLVED: To improve image quality by reducing mechanical stress applied to a toner in a developing apparatus, uniformly electrifying the toner, uniformly forming a thin layer on a developer carrier. SOLUTION: The toner T stored in a hopper 124 is supplied to an electrostatic carrying member 122 with a supply roller 123. The toner is carried and electrified by the work of the electrostatic actuator of the electrostatic carrying member 122, and the toner is supplied to the developing roller 121. A thin toner layer is formed on the developing roller 121 by the work of an electrical field. Since the toner is electrified, and the thin toner layer is formed without using a layer thickness control member such as a doctor blade, the mechanical stress applied to the toner is reduced.
