Abstract
A developer accommodating unit includes a developer accommodating unit formed by a developer accommodating frame and includes an integrally formed light guide member. The light guide member is mounted through the developer accommodating frame in a state in which an incident portion and an emergent portion are exposed through an incident side opening and an emergent side opening, respectively, and is connected with the developer accommodating frame in a sealed state so that an outside and inside of the developer accommodating chamber are prevented from communicating with each other via the incident side opening and the emergent side opening.
