PURPOSE:To prevent a drop of mixing, and to prevent clogging in a timmer part by providing a comb tooth-shaped member on a suitable place in a toner vessel, and moving it elastically up and down by an agitator. CONSTITUTION:A toner feed is executed to a developing device by attaching an auger 2 to the lower part of a toner vessel 1. An agitator 3 is placed so as to be rotatable in the center of the vessel 1, by which fluidity of a toner is improved, and generation of a toner bridge is prevented. A comb tooth-shaped member 4 is fixed like a horizontal plate to the lower part of the vessel and the upper part of the auger 2, and another sheet of comb tooth-shaped member 5 having elasticity is fitted like overlapping to the upper part of the member 4. Also, comb teeth 5a... of the member 5 and comb teeth 4a... of the member 4 are provided so as to be entered into each other, and a toner thrown into the vessel 1 passes through between these 4a... and 5a..., and drops toward the auger 2 of the lower part. A projection (b) of the member 5 contacts intermittently to the outside end part of the agitator 3. |
