US08494400B2 Developing device with moveable flexible sheet for preventing toner deposition on developing device casing and image forming apparatus including the same 有权
具有可移动柔性片的显影装置，用于防止显影装置壳体上的调色剂沉积和包括该柔性片的图像形成装置

Developing device with moveable flexible sheet for preventing toner deposition on developing device casing and image forming apparatus including the same
Abstract:
A developing device includes: a developer carrying member for supplying a developer to an image bearing member at an opposing region opposing to the image bearing member, the developer carrying member being arranged so as to be opposed to the image bearing member on which an electrostatic latent image is to be formed; a blade for regulating an amount of the developer carried on the developer carrying member; a casing for housing the developer carrying member and the blade, the casing including a wall portion opposed to the developer carrying member between the blade and the opposing region; a sheet member that is flexible, provided on the wall portion, has a free end, forms a part of an inner wall surface of the wall portion, and is movable in a direction perpendicular to the inner wall surface; and a moving portion provided on the wall portion, for moving the sheet member.
Abstract(Chinese):
