写機のトナ回収装置。[Scope of claim for utility model registration] Collecting untransferred developer containing magnetic material from a photoreceptor drum,
In a copying machine toner collection device that accumulates in a collection container,
The toner recovery device is connected to a coil that is disposed close to the top of the recovery container and whose inductance changes depending on the amount of developer accumulated in the recovery container; An oscillator whose output level changes due to a change in effective Q due to a change in inductance, and a level that identifies the output level of the oscillator and generates an output that indicates if the level changes outside of a predetermined range. a change detection circuit, whereby the detection circuit issues an alarm by the display output when developer reaches a predetermined amount in the recovery container.
