ABSTRACT:
To prevent degradation in printing precision with low cost even when a toner container is exposed to a high-temperature atmosphere, the toner container includes a resin molded article having a heat-insulating layer in it. The toner container may be multilayered, wherein at least one layer is a resin material including a heat-insulating material. The toner container may also be a resin molded article including a foam layer. The toner container may have a toner-filled-side surface, which is a fine-discontinuous-microstructure surface and a surface thereof not in contact with the toner, which is a smooth surface.
