PROBLEM TO BE SOLVED: To provide a toner replenishing device which can suppress occurrence of unpleasant noise by collision of toners against an inner wall of a carrier sheet while maintaining sufficient carrying capability of the toner. SOLUTION: Ribs 2, etc., are mounted to the top being a connection part with a top plate in a wall surface 22 of a toner housing part. Each rib 2 is separated and disposed in a direction (direction of arrow W) of a stirring shaft 13a of the stirring member 13 and formed as a platy member projected into the internal side of the toner housing part from the wall surface 22 by making the direction of separation into the thickness direction. Furthermore, a curved surface by which the end of the internal side of the toner housing part such as the ribs 2, etc., connects the top plate surface with the wall surface 22 smoothly is formed. That is, the curved surface includes the end of the internal side of the toner housing part as part for forming the curved surface of the ribs 2, etc., in the part of the rib. Then, part of the tip of a carrier sheet 14 in a bent state slides to the part for forming the curved surface of the ribs 2, etc., so that the whole tip of the carrier sheet 14 moves nearly on the curved surface. |
