Abstract: An image forming apparatus configured to execute image forming process by using hardware resources. The image forming apparatus includes a processor that executes application software including an image forming process, the application software causing display of one or more display screens. The image forming apparatus includes a display processing unit configured to display one of the one or more display screens on a display, a memory configured to store in association with each display screen, a power status indicating whether each of the hardware resources should be provided power during display of the display screen, a power status determining unit configured to determine which hardware resource should be provided power among the hardware resources, based on the displayed display screen and the power status stored in the memory, and a power control unit configured to provide power to the determined hardware resources.

Abstract: An image forming apparatus includes an engine configured to perform image formation; an engine control unit configured to control the engine; an apparatus control unit configured to control the whole of the apparatus; a storage unit; and a state management unit configured to set the apparatus to a power-saving mode in which the apparatus control unit and the storage unit are supplied with power while the engine, and the engine control unit are not supplied with power when a main power supply is turned on. When the apparatus is set to the power-saving mode, the apparatus control unit reads out second engine information that represents a configuration of the engine from the storage unit and performs a start-up process on the apparatus control unit on the basis of the second engine information.

Abstract: An image forming apparatus includes a reception part that receives, from a request part connected via a network, a power supply stop request that designates at least one of a plurality of power supply stop modes for stopping power supply in the image forming apparatus; a selection part that selects, when stopping the power supply in the image forming apparatus is not allowed in the designated power supply stop mode, power supply stop modes from the plurality of power supply stop modes in each of which stopping the power supply in the image forming apparatus is allowed; and a notification part that notifies the request part of the power supply stop mode selected by the selection part.

Abstract: An image processing apparatus includes an energy saving mode entering process part configured to associate each of plural functions and a minimum necessary energy saving mode of plural energy saving modes to perform the function as first information; and a counting process part configured to count a usage period of time for a used function of the plural functions for each unit period of time. The energy saving mode entering process part is configured to determine which of the plural energy saving modes to enter based on the counted usage periods of time for a present unit period of time and cause the image processing apparatus to enter the determined energy saving mode.

Abstract: An image processing apparatus, a method of controlling a power save state of the image processing apparatus, and a non-transitory recording medium storing a power save control program are provided. In response to detection of a power save transition factor that triggers transition to a power save state, the image processing apparatus determines whether a power save extension factor is detected, extends transition to the power save state at least during when the power save extension factor is being detected, and causes transition to the power save state according to the detected power save transition factor when the power save extension factor is not detected.

Abstract: An image processing apparatus includes a managing part to perform a first process to store the log information in a storage unit and a second process necessary to turn OFF a main power, a generating part to generate the log information by performing a third process necessary to turn OFF the main power, and to send to the managing part a first request signal causing the managing part to perform the first process on the generated log information, and a request part to send to the managing part a second request signal causing the managing part to perform the second process and to send to the generating part a third request signal causing the generating part to perform the third process, when a detecting part detects an OFF state of a main power switch.
