Abstract
A powdered developer supplying device in an electrostatic reproducing apparatus comprises a developer hopper and a developer receptacle. A cover for opening and closing a developer inlet opening of the developer receptacle is urged by a spring in the close direction. When the receptacle is installed on the hopper, the cover is opened by an operating member which is operated by the developer receptacle. A limiting member is provided for limiting movement of the cover from open/close positions. A bayonet type coupling member is provided for coupling the receptacle to the hopper by rotation after the receptacle is installed on the hopper. A developer receptacle wall which forms the bottom of the receptacle when the latter is up-ended at the time developer is being supplied is formed on a slope to facilitate flow of the powdered developer from the receptacle, through the opening into the hopper.
