Abstract
An interlocking mechanism for use in a developing device actuates a mechanism for regulating the condition of the developer on a developing roll correlatively with the movement of a developing unit from a developer supply location to a developer non-supply position and regulates to lower the height of the developer at the position where the developing roll faces the outside of the developing unit. The interlocking mechanism also stops the action of a structure which regulates the condition of developer correlatively with the movement of the developing unit from the developer non-supply position to the developer supply location.
