Abstract
An image forming apparatus includes a main body, a sheet cassette attachable to the main body and configured to support one or more sheets to be supplied to the image forming unit, and a controller. The main body includes an electrode movable relative to the main body, a capacitance detector configured to output a signal indicating a value corresponding to a quantity of electricity stored in the electrode, and a wire. The sheet cassette includes a metal member, and a sheet supporting plate made of metal, movable relative to the sheet cassette in an up-down direction, and configured to support one or more sheets from below. The controller is configured to determine whether the sheet cassette is at an installation position in the main body from a level of the value of the signal outputted from the capacitance detector connected to the electrode via the wire.
