Abstract: An electrical apparatus has a controller for switching between a normal power mode and power saving modes. A receiver receives instructions for a manipulation on the apparatus. A switch controller switches to a first power saving mode when no instruction for manipulation is received within a first standby time in the normal power mode, switches to a second and lower power saving mode when no instruction for manipulation is received and the time reaches a preset second standby time in the first power saving mode, switches to the normal power mode when an instruction for manipulation is received when the apparatus is in the first or second power saving mode, and switches to the second or a third power saving mode for supplying less power than the first power saving mode but more than the second when the time reaches the first standby time if a predetermined condition is satisfied.

Abstract: An image forming apparatus determines if a support function key is pressed down or not. When it is determined that the support function key is pressed down, the image forming apparatus determines if the read document is a one side document or a both-side document. Then the document is read and operable operational conditions are selected based on the read document and the information about an intended use that is inputted by a user. The selected operational conditions are displayed on an operating unit for each operational condition. As a result, it is possible to provide an image forming apparatus wherein the user can set a desired operational condition easily suitable for the user's intended use without omission and fail.

Abstract: An image forming apparatus includes an image forming unit, image formation control section, counter, image formation condition regulation section, controlled printed-paper number storage section, and regulation control section. The image forming unit includes a plurality of functional sections. The counter counts a cumulative printed-paper number in a series of image formation processing. The image formation condition regulation section regulates an image formation condition of at least one of the functional sections. The controlled printed-paper number storage section stores a benchmark printed-paper number and first allowable value to determine the timing of regulating the image creation condition. The first allowable value is set to be less than the benchmark printed-paper number.

Abstract: A warm-up execution portion 102 sets whether or not a color adjustment process is executed at a time of execution of a warm-up process. The warm-up execution portion (102) executes the warm-up process including a prescribed color adjustment process executed by forming a predetermined toner image on an image forming section (190) at a time of resume from a sleep mode or at a time of activating an image forming apparatus (10). When a setting portion (103) is set that the color adjustment process is not to be executed, the image forming section (190) is allow to execute the warm-up process excluding the color adjustment process.
