Claims

[Scope of utility model registration request]

a toner collection container that accommodates the residual toner removed from the photoconductor after transfer; a flexible film member that deflects in accordance with the amount of toner collected in the container; and a detected object that operates in accordance with the deflection of the film member. In a cleaning device for an electrophotographic recording machine that has a member and a detection control mechanism that detects the operation of the member to be detected, the operation of the member to be detected is detected in multiple stages, and the operation of the member to be detected is detected at each stage until the final stage. A cleaning device for an electrophotographic recording machine, which is equipped with a detection control mechanism that issues an appropriate warning and prohibits image forming operations at the final stage.
