The powder body filling up container and the picture formation device null which fill up the powder body with the powder body filling up device and its powder body filling up method of filling up the powder body with powder body filling up method and its powder body filling up method

摘要

PPROBLEM TO BE SOLVED: To provide a powder filling method which makes a powder filling device constituted as simple, small-sized and low-cost equipment, enhances the accuracy and efficiency of powder filling operations, and increases the bulk density of the infilled powder by preventing the deformation of a powder container, even if the powder is infilled at high speed, the powder filling device for infilling the powder by the powder filling method, a powder filling container which is filled with the powder by the powder filling method, and an image forming apparatus. PSOLUTION: After the powder container 1 is expanded by expansion pressure (Ip-Op) which is generated by a pressure differential (Ip-Op) between internal pressure (Ip) in the powder container 1 and external pressure (Op), the inside of the powder container 1 is deaerated by using deaerating pressure (Vp), so that the powder (t) can be infilled into the powder container 1 from a powder supply means 2.
