Title: Toner supply container
Inventor: BAN YUTAKA
IPC: G03G15/08
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a toner supply container which can be assembled satisfactorily and can also supply powder toner satisfactorily. SOLUTION: In a powder-toner storage part 1A, a carrying member 2 is provided for carrying powder toner to a powder-toner supply port 1 g by its rotation and then supplying it to a supply part. On the other hand, in the powder-toner storage part 1A, a stirring member 8, which swings toward the powder-toner supply port 1 g as the carrying member 2 rotates, is suspended, thereby causing the powder toner to fall down and securely supplying the powder toner without letting it remain there.
