DEVELOPING DEVICE AND IMAGE FORMING APPARATUS

Abstract: in a developing device including no supplying member for supplying a developer to a developing member, it is desired to simplify a configuration. a regulating blade includes a free end and a fixed end contacts a developing roller in a state in which the free end faces a downstream side in a rotational direction of the developing roller and regulates a thickness of a layer of the developer carried on the developing roller when an axis which passes through a rotation center of the developing roller and faces a direction opposite to a direction of gravity is a y-axis and an axis which passes through the rotation center and rotates the y-axis by � in a clockwise direction is an x-axis, in a coordinate system in which the rotational direction of the developing roller is a counterclockwise direction, the free end and the fixed end are disposed in a second quadrant of the coordinate system.
