Abstract
A developing device which can withstand resistance at a time a coagulated toner is scraped off is provided merely by providing a rotating shaft with a strength needed for agitating and conveying toner during normal operation. When the coagulated toner is scraped off, a large load is applied to the rotating shaft through an agitator. The rotating shaft bends, and a crank portion of the rotating shaft moves off of an axis. As a result, the crank portion is supported in a cut portion in a support plate. Therefore, strength of the rotating shaft becomes apparently greater. During normal operation, the crank portion of the rotating shaft moves out of the cut portion so as to be set in a state of non-contact with the cut portion. Therefore, no unnecessary load is applied to the rotating shaft, and the crank portion and the cut portion are not worn.
