An image formation apparatus includes: a control panel to receive an input of an operator; a main device to execute an operation instruction corresponding to the input; and a tilt changing section to change a tilt of the control panel relative to the main device. The control panel includes a touch panel having a touch surface to be touched, a control panel housing covering the touch panel, a proximity sensor to sense an object in the proximity of the control panel, and circuitry that: determines a presence or an absence of an operation of the tilt changing section by the operator based on a result of the sensing by the proximity sensor; outputs an operation instruction to the main device based on a touch input on the touch surface; and refrains from outputting the operation instruction based on a determination that the tilt is changed.
