Claim:
An image forming apparatus comprising: (a) an image processing section for generating image data for printing from image data inputted from an external apparatus; (b) an image forming section for forming an image from the image data generated by the image processing section; (c) a state detecting means for detecting a physical state of the image forming apparatus; (d) a processor configured to determine whether said image forming apparatus is in an ordinary physical state or an extraordinary physical state according to the physical state which is detected by said state detecting means; and (e) an operating mode changing means configured to change said image processing section between a first operating mode and a second operating mode, the second operating mode having heat emission less than in the first operating mode, wherein said image processing section is changed by said operating mode changing means from the first operating mode to the second operating mode when said processor determines that said image forming apparatus is in the extraordinary physical state, and wherein said image processing section is changed by said operating mode changing means from the second operating mode to the first operating mode when said processor determines that said image forming apparatus has returned from the extraordinary physical state to the ordinary physical state.
