    摘要: A developing device having a sealing construction for preventing a toner leakage therefrom. The developing device having a housing for accommodating a toner therein, a developing sleeve supported at the housing for holding a toner on a peripheral surface thereof, a scraper one end of which is supported at the housing and the other end of which is pressed in contact with the peripheral surface of the developing sleeve along an axial direction of the developing sleeve for regulating means for regulating an amount of the toner supplied to said peripheral surface of said developing sleeve. The space among the housing, the developing sleeve and the scraper is sealed by a square-frame shaped seal member.

    摘要: The invention provides image forming method and apparatus. One embodiment of the invention is an image forming apparatus with a developing device. This apparatus also includes: (1) an electrostatic latent image carrier on which an electrostatic latent image is formed, (2) a developing roller rotatably driven in a first direction during developing, (3) a developing-roller-reverse rotator which rotates the developing roller in a second direction opposite the first direction, when the developing device moves with respect to the electrostatic latent image carrier. Another embodiment is an image forming apparatus that also includes a developer-regulating member positioned in direct contact with or close proximity to the developing roller. In this embodiment, the rotation of the developing roller in the second direction dislodges materials stuck between the developing roller and the developer-regulating member. Yet another embodiment of the invention an image forming apparatus that also includes a developing device, an electrostatic latent image carrier, a developing roller, and a developer-regulating member. This embodiment further includes a separating member coupled to at least one of the developing-regulating member and the developer roller. The separating member moves the developer-regulating member and the developing roller away from each other when the developing device moves.

    摘要: In an image forming apparatus, a toner image, formed by developing an electrostatic latent image on the photoreceptor, is primarily transferred to an intermediate transfer member and is secondarily transferred to a recording sheet. The image forming apparatus is provided with a retractable transfer member, which secondarily transfers the toner image on the recording sheet, and a retractable cleaning member, which removes a residual toner on the intermediate transfer member after the secondary transfer. In the above apparatus, when the primary transfer and the secondary transfer are not being performed, the transfer member and the cleaning member are allowed to contact with or retract from the intermediate transfer member.
