The present invention discloses an image forming apparatus and an image forming method. An apparatus body implements plural functions including an image reading function, an image forming function, and a display function. A controller controls first, second, and third power states, wherein the first power state is a state in which one of the plural functions is being performed, the second power state is a state in which one of the plural functions is ready to be performed, the third power state is a state in which there is no power to perform any of the plural functions or the third power state is a state in which power is lower than power in the first power state or the second power state; an obtaining unit that obtains information concerning paper. A first control unit controls the plural functions so that, when the plural functions are returned from the third to the second power state, the display function is returned to the second power state without being synchronized with the other functions and an operation requested is received before the other functions are returned to the second power state. A second control unit controls the other functions so that, if the image forming function executs an operation requested, the operation is executed after the obtaining unit obtains the information concerning paper.
