Title: Magnetic toner and production of magnetic toner
Inventor: YUASA YASUHITO
IPC: G03G9/08
Filed: 1993-11-16
Abstract: PURPOSE:To enable recycling of a waste toner to be conducted, to prevent filming of a photoreceptor and to obtain high picture qualities with high density and low fog by subjecting a magnetic toner to external addition treatment under reduced pressure. CONSTITUTION:The magnetic toner 26 consists of at least a binder resin, magnetic material and external additive. The external addition treatment to mix and deposit the external additive to the toner base body is performed in a mixing tank 20 of a specified volume by using a mixing means comprising a rotor 21 which can rotate and gives shearing force to the powder under reduced pressure of the tank 20. Air in the powder layer can be removed by mixing under reduced pressure, so that the apparent specific gravity is increased and shearing force necessary for mixing can be effectively given. Thereby, pulverization of silica fine particles can be sufficiently performed and toner fine particles and silica fine particles having different specific gravities from each other can be uniformly mixed. As a result, the toner 26 has high electrification characteristics and high fluidity.

IPC: G03G15/08
Filed: 1991-10-31
Abstract: PURPOSE:To eliminate fogging and to form a high-density image without requiring the adjustment and impression of a development bias voltage by providing an electret layer having a specific relation between a charge density, thickness and specific dielectric constant on the surface of a developer transporting member. CONSTITUTION:The developer transporting member has the electret layer satisfying equation I on the surface. In the equation I, V1 denotes the surface potential (volt) of a high-voltage part of a supporting member; V2 denotes the surface potential (volt) of a low-voltage part of a supporting member; sigma denotes the charge density (coulomb/V.m) of the electret; (d) denotes the thickness of the electlet; epsilon(0) denotes the dielectric const. (coulomb/V.m) of vacuume; epsilon is the specific dielectric constant of the electret, where the polarities of V1, V2 and sigmaare the same. As a result, the developer is electrostatilly stuck to the electrostatic latent image to be developed without impressing the bias voltage or without the need for adjusting the voltage. On the other hand, the sticking of the developer to the background is electrostatically suppressed.
