摘要： An image developing method is disclosed that is able to efficiently remove degraded toner on a developing agent carrier, prevent formation of abnormal images, ensure good image quality over time, and increase the service life of the device. The developing method includes a step of calculating an amount of consumption of the developing agent during image formation and an amount of consumption of the developing agent in a compulsory toner consumption mode under different calculation conditions between the image formation and the compulsory toner consumption mode. In the compulsory toner consumption mode, a developing bias different from a developing bias used during image formation is applied for a predetermined time period to discharge residual developing agent on a developing agent carrier to a latent image carrier.

摘要： A toner bearing body unit is constituted as one assembled unit including a toner bearing body for holding toners supplied from a toner supply roller of a housing main body at an outer peripheral surface thereof, a toner layer thickness regulating member for electrically charging the toners by applying pressure toward the outer peripheral surface of the toner bearing body and for forming a toner thin layer on the toner bearing body, and a holding member for holding the toner bearing body and the toner layer thickness regulating member. The toner bearing body unit is constituted to be directly attachable to and detachable from an outer side of the housing main body of a developing apparatus. Accordingly, an uniform toner thin layer having a predetermined thickness can be formed stably on the toner bearing body during a long period of use, and the developing apparatus reconstructed so that replacement of the components thereof can be carried out easily. Further a developing apparatus having a good recycling performance can be provided.
