To provide a toner cleaning chamber for cleaning components to which toner is deposited.
In the chamber, air flows along a rectification plate, thereby preventing air from stirring up in the upper space of a first chamber part and returning to a worker S (forward opening 12 side). Moreover, hemispheric peaks 22A and hemispheric troughs 22B are formed on the inner wall surface, and the air smoothly flows by a rectification effect (aerodynamics) eliminating turbulent flows. Furthermore, air jets out from a jet port of a pipe to form an air curtain E at the boundary between the inside and outside of the forward opening, thereby eliminating a flow returning to the worker S from the forward opening. According to the curtain E between the worker S and the forward opening 12, the air suction from the opening is hardly affected by the worker S standing. The air is stably and smoothly exhausted from the forward opening 12 to the rear opening 14, thereby preventing the toner blown away by air gun from stirring up inside of the first chamber part or returning to the worker S. As a result, the chamber for cleaning toner with excellent workability is provided.
