Abstract
According to one embodiment, the information processing apparatus includes an acquisition unit, a derivation unit, and a determination unit. The acquisition unit acquires voltage information indicating a voltage applied to a heat generation unit that heats a sheet in an image forming apparatus. The derivation unit derives a fluctuation range in the voltage indicated by the voltage information acquired by the acquisition unit. The determination unit determines whether or not there is an indication of a malfunction in the heat generation unit using the fluctuation range derived by the derivation unit and a reference fluctuation range.
