Toner carrier apparatus, toner feeding apparatus, and image forming apparatus

摘要

Accumulation and coagulation of toner inside a vertically-disposed toner carrying path is properly prevented. The toner carrier apparatus includes: a toner carrier pipe which includes therein a toner carrying path through which toner is carried and is disposed so that the toner carrier path vertically extends; a pipe supporting member which supports the toner carrier pipe in such a way as to allow the toner carrier pipe to be vertically movable; a rotational member and operation wings, which cause the toner carrier pipe to reciprocally move in the vertical direction and horizontally swing; and a knocking mechanism which horizontally hits the toner carrier pipe.
