Abstract
A toner hopper is arranged to feed the toner stored in itself to a developing unit and have a stirring roller and a feeding roller respectively supported rotatably, an interlocking mechanism for transmitting the force of rotation to the stirring roller, a manually rotating mechanism for manually rotating the stirring roller, and an interlocking restricting mechanism. The interlocking mechanism restricts the operation of the interlocking mechanism such that the force of rotation of the stirring roller is not transmitted to the feeding roller while the manually rotating mechanism supplies force of rotation to the stirring roller.
