Abstract
A developing device includes a developing container for accommodating a developer; a developer carrying member, provided rotatably in the developing container, for carrying and feeding the developer to develop an electrostatic image; a developer feeding member, including an elastic feeding portion and being rotatably provided in the developing container, for feeding the developer in the developing container toward the developer carrying member; and a circulation changing member for changing circulation of the developer in the neighborhood of the developer carrying member. In a plane perpendicular to a rotational axis of the developer carrying member, the circulation changing member is provided in a maximum rotation area of the developer feeding member so as to create a gap between itself and an entire inner surface of the developing container and a gap between itself and the developer carrying member.
