PROBLEM TO BE SOLVED: To provide an electrophotographic device capable of accurately displaying the residual amount of toner. SOLUTION: A circular arc-shaped plate D4 is provided in a tank 12 on a cartridge 1 side, and plural plates D1 to D3 are provided in an up-and-down direction in parallel with the plate D4 on the outside of the tank 12. Then, sensors 5, 6 and 7 detecting the electric capacity of the plates D1 to D3 of a capacitor consisting of the plate D4 and the plates D1 to D3 are provided on a main body side, and the residual amount of the toner is judged by a control part 11 by using the detection signals from the sensors 5, 6 and 7 and the judged result is displayed on a residual amount display panel 8. |
