Abstract:
1. An image forming apparatus having a communication unit for receiving document data over a network, a storage unit for accumulating the document data in a document box, and a printing unit for printing the document data, comprising: a frequency-of-use measuring unit for measuring a frequency of use of a predetermined function, a power cutoff period identifying unit for identifying a power cutoff period for turning off power for the image forming apparatus on the basis of the frequency-of-use measured by the frequency-of-use measuring unit; a document data processing unit for printing and erasing the document data accumulated in the document box prior to the power cutoff period, a power management unit for turning off the power for the image forming apparatus upon the power cutoff period being reached with the document data being not accumulated in the document box; an image processing unit for converting the document data into encrypted image data, and the document data processing unit for using the image processing unit to convert the document data accumulated in the document box into encrypted image data prior to the power cutoff period for printing it; and wherein the power cutoff period identifying unit identifies a time span in which a unit period of time in which none of the functions is used is repeated a predetermined number of times or more, as the power cutoff period, and wherein, the power cutoff period identifying unit can set the unit period of time to be measured as a time none of the functions for user login, network reception, and facsimile reception is used, or one or more of these are not used.
