An image forming apparatus includes the following elements. An apparatus body implements plural functions including an image reading function, an image forming function, and a display function in accordance with operations requested by a user. A controller controls first, second, and third power states. An obtaining unit 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 by the user 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 is required for executing an operation requested by the user, the operation is executed after the obtaining unit obtains the information concerning paper.

Image forming apparatus and computer readable medium

Provided is an image processing apparatus including a mode switching unit that selectively switches a mode between a rapid heating mode and a heat accumulating mode in a fixing unit, a receiving unit that receives an image formation request received from the outside, an extracting unit that extracts mode switching determination information at the earliest from the image formation request received by the receiving unit, a selecting unit that selects the mode based on the mode switching determination information extracted by the extracting unit, specifications of the fixing device, and a current temperature, and a switching control unit that controls the mode switching unit based on the mode selected by the selecting unit to switch the mode to the rapid heating mode or the heat accumulating mode.

Image processing apparatus, computer readable medium, and image processing method with dual heating modes

An image processing apparatus includes an image forming section, a fixing section, a mode switching section that selectively switches a fixing mode between a fast heating mode and a heat accumulation mode, a selecting section that selects the fast heating mode or heat accumulation mode based on the relationship between operation expressions F1+P1&#xd7;N and W+F2+P2&#xd7;N, where N is the number of sheets to process, F1 is the time from instruction of processing in fast heating mode to processing start, P1 is the per-sheet processing time in fast heating mode, W is the warm-up time for the heat accumulation mode, F2 is the time from instruction of processing in heat accumulation mode to processing start, and P2 is the per-sheet processing time in heat accumulation mode, and a switching controller that controls the mode switching section to switch to the fast heating or heat accumulation mode based on the selected mode.
