Abstract
An image forming apparatus includes a sheet cassette, a waste developer container, a capacitance sensor, a partition conductor, and a state determination unit. The waste developer container is disposed adjacent to the sheet cassette, and the capacitance sensor is disposed between the waste developer container and the sheet cassette. The partition conductor partitions between the sheet in the sheet cassette and the capacitance sensor, and is grounded. The state determination unit determines an amount of the waste developer in the developer container, based on a detection signal of the electrostatic capacitance sensor.
