Abstract

A developing device (11) includes a toner supplying roller (21), a developing roller (20) for transferring a one-component toner to a developing position by performing a developing rotation in an image forming operation and moving away from the developing position, a sealing member (30) arranged in a vicinity of the developing roller (20), and a toner layer regulating roller (22) arranged in contact with the developing roller (20) for locking a rotating operation in the image forming operation, for regulating the one-component toner which adheres on a surface of the developing roller (20) into a thin layer and for freely following the developing roller (20) in a non-image forming operation.

Description

technical field [0001] The present invention relates to a developing start-up method used in electrophotographic image forming apparatuses such as copiers, facsimile machines, and printers, a developing apparatus, and a process cartridge. More specifically, the developing apparatus uses a single-component toner and is provided with A developing roller and a doctor roller. The doctor roller is in contact with the developing roller so that the toner layer on the developing roller becomes a certain thin layer. Background technique [0002] Conventionally, in a developing device using a single-component toner, a constant amount of toner layer is formed by frictionally charging toner supplied from a supply roller to the developing roller at the contact portion between the toner layer restricting member and the developing roller. As the toner layer restricting member for regulating the thickness of the toner layer on the developing roller, a scraper member is generally used. When ...
