Abstract
It is determined whether a performing condition for first welding detection is satisfied. If the performing condition for the first welding detection is satisfied, the first welding detection is performed. On the other hand, if the performing condition for the first welding detection is not satisfied, the first welding detection is skipped. The performing condition for the first welding detection is that second welding detection has detected welding of a relay. The first welding detection is performed before image formation is performed. The second welding detection is performed after image formation has ended.
