Abstract
A developing device includes a developing container for accommodating a developer, a rotatable developer carrying member for carrying and feeding the developer, and a layer thickness regulating member for regulating a layer thickness of the developer carried on the developer carrying member. The developer circulates between first and second chambers, which are partitioned by a partition wall. A rotatable feeding member feeds the developer in the first chamber, and a light-transmitting portion permits light transmission into a developing container. The light-transmitting portion is disposed at a developer carrying member side of the partition wall so that a light beam entering inside of the developing container is regularly reflected by a surface of a rotation shaft of the feeding member, and the regularly reflected light is emitted outside of the developing container through a gap between the developer carrying member and the layer thickness regulating member.
