Claims

[Scope of Claim for Utility Model Registration] (1) A toner remaining amount detection device and a toner cavity prevention means in a hopper in which toner is stored;
A flexible member fixed to the vibrating member of the hollowing prevention means is provided, and the vibration of the vibrating member causes the tip of the flexible member to come into contact with the detection surface of the remaining toner amount detecting means. A toner replenishing device characterized by being designed to peel off toner adhering to a detection surface. (2) The toner according to claim 1, wherein the vibrating member to which the flexible member is fixed is vibrated by driving rotation of a toner replenishing roller provided near the bottom opening of the developer hopper. Supply equipment.
