PURPOSE:To prevent a toner from adhering and being piled up even in case of a small air flow by providing a low surface energy layer on the inside surface of an outflow path for attracting and collecting the toner removed by a brush roll. CONSTITUTION:A residual toner of a photosensitive body 1 is removed by a magnetic brush roll 5 in a housing 4. This toner is attracted by an attracting means connected to the housing through an outflow path 7 and a duct line 8. A low surface energy layer 9 is provided on the inside surface of this outflow path 7, the toner does not adhere nor is piled up in the outflow path 7 even in case of a small air flow, and the cleaning is executed satisfactorily. Also, even if the toner is piled up by use of a long period of time, it is removed easily since the layer 9 is provided. |
