PURPOSE:To improve the efficiency of filling by giving an air pressure in a vertical direction to the upper surface of a toner layer supplied in a container. CONSTITUTION:An attachable/detachable cover body 3 is pressed on the opening part of the container 1 and the air pressure (a) is given to the upper surface of the toner 2 from an opening part 7 provided in the center part of the cover body 3 through an air pressure induction member 8. A rubber packing 4 is provided below the cover body 3 so as to improve tightness between the cover body 3 and the container 1. Therefore, press-tightening can be performed by giving a power except a gravity to the toner particles. Thus, the efficiency of filling toner can be remarkably improved and the pulverization of the toner particles and the adhesion to the container can be prevented. |
