Abstract

PURPOSE:To stably secure appropriate image density for a long period by providing a turn operating member for a developer in a developer container in the container, and providing a means which changes the turning speed or the turning locus, or both of them of the turn operating member. CONSTITUTION:Corresponding to the state change of the quantity of the developer or environmental humidity that is the fluctuation factor of the image density, the agitating state of the developer in the developer container 1, the carrying state of the developer in the direction of a developing sleeve 2 that is a developing member, and the state of a developer collecting convention part on the developing sleeve 2 side are controlled appropriately at respective state by the control of the rotating speed and rotating locus of first and second rotational bar members 11 and 21 as the turn operating member. Therefore, it is possible to apply the developer having required and sufficient electrified charge on the plane of a latent image supporting body 100 by supporting and carrying the developer to the developing sleeve 2 that is the developing member in spite of each state change. In such a way, it is possible to secure the appropriate image density stably for the long period.
