Abstract
A heating apparatus includes a switching circuit configured to switch on/off current-feeding from an AC power source to the heater, a temperature detector configured to detect a temperature of the heater, and a current-feed controller configured to execute a first current-feed mode of changing a current-feed ratio of current-feeding time to unit time by controlling switching of the switching circuit so that the temperature detected by the temperature detector falls within a target range. The current-feed controller executes a second current-feed mode of fixing the current-feed ratio to almost 100% or almost 0% during execution of the first current-feed mode in place of the first current-feed mode.
