Claims

[Claims for Utility Model Registration] (1) A developer replenishment container, a sensor provided in the container to detect the presence or absence of developer, and a support shaft proximate to the sensor, capable of rotating within the above description. What is claimed is: 1. A developer detection device comprising: a support member provided thereon; and a cleaning member provided so as to be floatingly fitted onto a support shaft of the support member so as to be able to come into contact with the sensor within its swing range. (2) The developer detection device according to claim 1, wherein the cleaning member has a spiral structure.
