    Abstract: An image forming apparatus capable of preventing misdetermination of a type of printing paper includes a transmitted light receiver, a specularly reflected light receiver, and a diffusively reflected light receiver, which constitute a sensor, and an output determiner that determines whether data output by the plurality of light receivers is normal. The image forming apparatus determines the type of printing paper and an abnormality of the printing paper from the determination by the output determiner.

    Abstract: Provided are an apparatus and a method of detecting an error in the apparatus. The apparatus includes an image former and an induction heating fusing device. The image former forms an image. The induction heating fusing device fuses the image formed by the image former onto paper. Whether the apparatus has an error is determined by limiting a current applied to a resonance circuit included in the induction heating fusing device to less than a certain level.
