Abstract
A developing device includes an accommodating member, a developer carrying member, a feeding screw provided with a helical blade, a bearing portion, and a guiding portion including an inclined surface. With respect to the developer feeding direction, a position of an edge of a receiving port of the accommodating member on a bearing portion side is closer to the bearing portion than a most-upstream end of the blade with respect to the developer feeding direction. With respect to the developer feeding direction, a position of a downstream end portion of the inclined surface is remoter from the bearing portion than the most-upstream end of the blade with respect to the developer feeding direction.
