ABSTRACT:
A device for developing an electrostatic latent image includes a developing roller disposed in a developing housing and a developing agent-limiting device for limiting the amount of the developing agent held on the peripheral surface of the developing roller. The developing agent-limiting device includes a flexible blade brought into pressed contact with the peripheral surface of the developing roller, a flexible support plate that is mounted on the blade and supports the blade in a predetermined positional relationship with respect to the developing roller, and a resilient urging device that is constituted by a plurality of spring members arranged on the back surface of the support plate at a distance in the direction of width thereof and pushes the blade in a direction in which it comes into pressed contact with the peripheral surface of the developing roller via the support plate.
