To improve a toner container that has a toner bag, so as to be easy to manufacture and excellent in practicality.

A flexible bag member (95) has a weldable layer (92) made of a easily weldable material, an airtight layer (93) made of a material excellent in gastightness, and a rigid layer (94) made of a material excellent in rigidity. The bag member (95) is formed by folding the laminate sheet material and welding the opposite edges of the weldable layer. Further, the flexible bag member (95) is provided with a mouthpiece member (96) welded to the weldable layer and having a through-hole (89) by which the inside and outside of the bag member communicate with each other. In the bag member, the weldable layer, gastightness layer and rigid layer are disposed in that order from inside. Forming the bag member from the weldable layer, gastightness layer and rigid layer makes it possible to obtain a toner container excellent in three properties, that is, weldability, gastightness and rigidity.
