PURPOSE:To obtain a dust collector by which a developer can be always stably collected without causing blinding even in the case of sucking a large amount of the developer by vibrating a suction nozzle. CONSTITUTION:By rotating a developing sleeve 4 in a developing unit 2 at the time of copying action, a suction nozzle 3 is vibrated. As a result, a trouble such as causing blinding by sticking a toner to the periphery of an opening 3a and its inside, in the case of sucking, for instance, a large amount of the toner from the opening 3a of the nozzle 3, is avoided, and the above-mentioned toner can be efficiently collected always in a stable condition. Thus by enabling the toner to collect in the always stable condition with no blinding, a trouble, such that the scattered toner adheres onto transcription paper to deteriorate picture quality, is avoided. |
