Waste toner collector and image forming apparatus

摘要

A waste toner collector of the present invention includes: a container main body configured to collect and store waste toner; and a conveyance member configured to convey the waste toner in the container main body. The container main body is provided with, on one side wall, a plurality of protruding containing portions that protrude outward from the container main body and are disposed along a longitudinal direction of the container main body, and a plurality of recesses each positioned between adjacent ones of the protruding containing portions. The conveyance member extends along the longitudinal direction of the container main body and is rotatably disposed in the container main body. Waste toner conveyance force of the conveyance member in a rotary shaft direction varies in such a manner that, at border portions between the protruding containing portions and the recesses, the waste toner is pushed toward the protruding containing portions.

主权项

1. A waste toner collector comprising:
a container main body configured to collect and store waste toner; and a conveyance member comprising a rotary shaft which extends along a longitudinal direction of the container main body, the conveyance member being configured to convey the waste toner in the container main body along a rotary shaft direction corresponding to the longitudinal direction of the container main body, wherein the container main body is provided with, on one side wall, a plurality of protruding containing portions that protrude outward from the container main body and are disposed along the longitudinal direction of the container main body, and a plurality of recesses each positioned between adjacent ones of the protruding containing portions, wherein the conveyance member is rotatably disposed in the container main body, wherein the conveyance member is configured to have a variable waste toner conveyance force along the rotary shaft direction in which the waste toner is conveyed, the waste toner conveyance force being a force which conveys the waste toner in the rotary shaft direction, and wherein the waste toner conveyance force of the conveyance member is varied along the rotary shaft direction to be larger at portions of the rotary shaft corresponding to the protruding containing portions than at portions of the rotary shaft corresponding to the recesses, the waste toner conveyance force varying at border portions between the protruding containing portions and the recesses, such that at the border portions, the waste toner is pushed toward the protruding containing portions.
