摘要： An apparatus develops an electrostatic latent image on a charge-retentive surface. A donor roll is selectably rotatable in a process direction and in a reverse direction relative to the process direction. A toner mover loads toner particles onto a portion of the surface of the donor roll. A metering blade is disposed downstream of the toner mover in the process direction. A seal is disposed upstream of the toner mover in the process direction, and is adapted to remove at least approximately half of the undeveloped toner from the donor roll.

摘要： An elastic rotation body contacts with the surface of a developer carrier and rotates in the same direction as that of the carrier. A bias voltage for forming an electric field for attracting a developer on the carrier which has passed through a development station is applied to the elastic rotation body. The elastic rotation body is disposed at the edge portion of an opening of a device housing in the downstream of the development station, in such a manner that a part of the surface of the elastic rotation body is exposed to the outside of the device housing, and the clearance between the rotation body and the electrostatic latent image holder is greater than the clearance between the developer carrier and the electrostatic latent image holder. A developer removing member for returning the developer on the elastic rotation body to the interior of the device housing is disposed. The rotation body can prevent the image hysteresis phenomenon from occurring and reduce the toner scattering to a very small degree, without deteriorating the charging property of the developer.

摘要： A toner scraper includes a rubber member which is to be contacted with the rotation body of a developing device, and a plate spring member for elastically supporting the rubber member which is fixed to the front end portion of the plate spring member, wherein at least an edge portion of the rubber member which is in the side of a portion of the plate spring member at which the plate spring member is supported is contacted with the surface of the rotation body.Such a toner scraper which is contacted with a roll or belt-like rotation body disposed as a component of a developing device and which scrapes off a toner adhering to the surface of the rotation body is configured so that the scraper can scrape off the toner uniformly and stably even when the contact pressure is relatively low, the scraper can be produced at a low cost, and the scraper has a simple structure.

摘要： Disclosed is a one-component developing apparatus in which a developing agent scale-off member such as a wire member is provided parallel to the surface of the developing agent carrier so as to be in contact with or in close proximity to a developing agent carrier. A developing agent thin layer formed on the surface of the developing agent carrier which did not contribute to development in a development region comes into contact with the developing agent scale-off member so as to be forcibly scaled off of the developing agent carrier, so that the image history is erased. When the developing agent scale-off member is made to vibrate, or a bias voltage is applied between the developing agent scale-off member and the developing agent carrier, the developing agent may be scaled off more efficiently.
摘要翻译：公开了一种单组分显影装置，其中诸如线材的显影剂去除构件平行于显影剂载体的表面设置成与显影剂载体接触或接近显影剂载体。在显影剂载体的表面上形成的显影剂载体的显影剂载体的显影剂薄层与显影剂剥离部件接触，从而显影剂载体被强制地剥离，使得图像历史被删除。当使显影剂降低构件振动或者在显影剂剥离构件和显影剂载体之间施加偏压时，可以更有效地缩放显影剂。
