Claims

[Scope of utility model registration request]

A cylindrical toner cartridge having a slit-like opening in the longitudinal direction is provided with a flange having a recessed part on the inner circumference through which a protruding part protruding radially outward from the flange provided near the front end of the toner cartridge is provided. The protruding portion is inserted into a cylindrical casing fixed to a machine frame by passing through the recessed portion, and the toner cartridge is rotated within the casing when the developing device is operated. When the toner cartridge is removed, the toner cartridge is supplied with toner into the developing device through a toner supply means, and when the toner cartridge is removed, the cylindrical grip portion of the toner cartridge protruding toward the front side from the flange is grasped by hand, and the protruding portion of the flange is pressed against the casing. In a toner replenishment device for a developing device of an electrostatic recording device, the toner cartridge is rotated to a position that coincides with the recessed part of the flange of the casing flange, and the toner cartridge is pulled out toward the user. a stopper movable in the axial direction along the downstream end face of the rotation direction between a position protruding inward from the flange inner surface and a position retracted outward from the flange inner surface; and a stopper implanted on the outer surface of the casing flange. a set position which is pivotally supported by a pin and has one end protruding into the range of the flange of the toner cartridge and the other end displacing the stopper to a retracted position and holding it at that position;
A lever is provided which is movable between one end of the stopper retracted from the range of the flange of the toner cartridge and a release position where the other end displaces the stopper to a protruding position and holds the stopper at that position. Toner supply device.
