Abstract

A developer layer thickness regulating device includes a blade member for regulating a thickness of a layer of a developer on a surface of a developing roller rotatably supported by a developing container for accommodating the developer and includes a supporting member for supporting the blade member. The supporting member is capable of being fastened to a part of the developing container by a fastening member, and a position of the supporting member relative to a part of the developer container is adjustable with respect to a widthwise direction of the blade member, when the supporting member is fastened to the developing container by the fastening member, so as to fasten the blade member at a predetermined position relative to the developing container. The supporting member has a projection-recess portion which is capable of biting into the part of the developing container when the supporting member is fastened by the fastening member.
