Title:
DEVELOPING DEVICE AND IMAGE FORMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/042882
Kind Code:
A1
Abstract:
For a developing device having no supply member for supplying a developing agent to a developing member, further simplification of the configuration is desired. A regulating blade 44 has a free end 44a and a fixed end 44b. The free end 44a abuts against a developing roller 42 in a state of being oriented to the downstream side of the rotation direction of the developing roller 42, whereby the thickness of a layer of a developing agent supported on the developing roller 42 is regulated to a prescribed thickness. In a coordinate system where an axis that passes through the rotation center of the developing roller 42 and that is oriented reverse to the gravity direction is defined as a Y axis, an axis that passes through the rotation center and that results from rotation of the Y axis by 90° clockwise is defined as an X axis, and the rotation direction of the developing roller 42 is counterclockwise, the free end 44a and the fixed end 44b are disposed in the second quadrant of the coordinate system.
