Abstract
PURPOSE:To prevent the creeping of a developer carrying member or a latent image carrier with a simple constitution, by specifying forces for the developer carrying member when rotation-enabled members of a 1st press-contacting member and a 2nd press-contacting member stop the rotation as well as when they are rotated and frictional force works to both of them. CONSTITUTION:When a thinly layering roller 9 stops its rotation, a developing roller 6 receives the force P by means of the thinly layering roller 9 and a blade 10. If the force P becomes smaller than the force Q that the developing roller 6 receives from both members 9 and 10, or becomes '0' or becomes negative when the thinly layering roller 9 rotates to execute a developing action, the pressurizing force to the developing roller 6 can be made smaller than the pressurizing force at the time of developing actions or can be made '0'. Namely, by properly setting the direction and the size of a force given to the thinly layering roller 9 by the blade 10, the force given to the developing roller 6 from the thinly layering roller 9 side is made smaller to be satisfactorily set '0' (Q>P, it is satisfactory to set P<=0). Thus, the creeping of the developing roller 6 can be reduced or prevented.
