Abstract:
An image forming apparatus includes a storage chamber configured to store developer, a plurality of sheet members disposed between a first electrode and a second electrode and disposed in the storage chamber, and a detecting portion configured to detect an output value relating to the capacitance between the first electrode and the second electrode. The amount of the developer is detected on the basis of the degree of deterioration of any one of the plurality of sheet members and the output value.
