摘要： A device is provided for developing an electrostatic latent image formed on an image bearing member with a developer comprised of magnetically attractable, electrically insulating toner particles for developing the latent image by applying the toner particles in the form of a thin film uniform in charge and thickness. The developing device generally comprises a developing sleeve, which is driven to rotate to carry thereon toner particles, and a pressure plate is held in pressure contact with the sleeve to thereby form a thin film of charged toner particles on the sleeve upstream of the developing station. In one aspect of the present invention, the pressure plate has a low hardness or relatively easily wearable region which is in pressure contact with the sleeve so as to prevent toner particles from permanently sticking to the pressure plate. In another aspect, the pressure plate is structured to have a locally defined relatively easily deflectable region which is in pressure contact with the sleeve. In a further aspect, the pressure plate is movable with respect to the sleeve to thereby remove stuck toner particles from the pressure plate and from the sleeve. In a still further aspect, a separator strip is provided, interposed between the pressure plate and the sleeve, which also keeps toner particles from sticking to the pressure plate. In a still further aspect, a cleaner is provided for cleaning the pressure plate periodically or continuously in order to keep toner particles from sticking to the pressure plate and to allow a thin film of uniformly charged toner particles to be formed on the sleeve for use in developing the latent image at the developing station.
摘要翻译：提供一种装置，用于通过将具有均匀电荷和厚度的薄膜形式的调色剂颗粒与由可吸引的电绝缘调色剂颗粒组成的显影剂显影在图像承载部件上形成的静电潜像，用于显影潜像。显影装置通常包括显影套筒，其被驱动旋转以承载调色剂颗粒，并且压力板保持与套筒压力接触，从而在显影台上游的套筒上形成带电调色剂颗粒的薄膜。在本发明的一个方面，压板具有与套筒压力接触的低硬度或相对容易穿戴的区域，以防止调色剂颗粒永久地粘附在压力板上。在另一方面，压板被构造成具有与套筒压力接触的局部限定的相对容易偏转的区域。在另一方面，压板可相对于套筒移动，从而从压板和套筒中去除粘附的调色剂颗粒。在另一方面，提供了隔离带，介于压板和套筒之间，这也使调色剂颗粒不会粘附到压板上。在另一方面，提供一种清洁器，用于周期性地或连续地清洁压力板，以便使调色剂颗粒不会粘附到压力板上，并且允许在套筒上形成均匀带电的调色剂颗粒的薄膜，以用于在开发站发展潜像。

摘要： A device for developing an electrostatic latent image formed on a photosensitive member includes a developing sleeve which is driven to rotate in a predetermined direction and a pressure blade which is kept pressed against the sleeve to form a thin film of uniformly charged toner so as to apply for the latent image for development. In accordance with the present invention, the forward end portion of the pressure blade is specifically shaped such that a projection having the width which substantially corresponds to the width of an image forming area of the photosensitive member is provided to extend beyond a contact line between the sleeve and the blade thereby allowing to form the thin film of toner whose width substantially corresponds to the image forming area of the photosensitive member, thereby preventing the waste of toner from occurring.
