A toner current measuring device able to measure a toner current. The toner current measuring device having provided therein a toner deposit capacitor c 1 including an electrode 11 and an electrode 12 disposed in opposition, a reference capacitor c 2 having a mechanism for adjusting a capacitance thereof; a power supply unit 4; and a measuring unit 10 for measuring, when a voltage is applied to both capacitors to cause a transfer, between the opposing electrodes, of charged toner deposited on the electrode 11, a difference between currents flowing in the toner deposit capacitor c 1 and the reference capacitor c 2, the difference being measured as a toner current generated as a result of the transfer of the charged toner.
