Abstract
A remaining toner amount detecting apparatus includes two electrodes; a remaining toner amount detector configured to detect a remaining toner amount in a toner container based on a capacitance between the two electrodes; a storage configured to store a first capacitance value between the two electrodes preliminarily detected in a non-disposed state in which the toner container is not disposed between the two electrodes; and an abnormality detector configured to detect an abnormality of the remaining toner amount detecting apparatus based on the first capacitance value stored in the storage and a second capacitance value between the two electrodes that is detected in the non-disposed state.
