Abstract: An image forming device includes a control unit and a storage unit, where the control unit determines whether or not data for printing which has been inputted while a power save mode is being executed has a control command appended to reduce electrical power consumption. If it is data for printing to which the control command is appended, then the control unit does not execute any image forming operation, but instead stores this data for printing with the control command appended in the storage unit. However, if data for printing to which no control command is appended is inputted, then the control unit, after performing an image forming operation for this data, performs an image forming operation for data for printing with the control command appended within the storage unit, which has the same identification information as the data for printing to which no control command is appended.

Abstract: The image forming device of this invention includes a control unit and a storage unit. The control unit determines whether or not data for printing which has been inputted while the power save mode is being executed is data for printing to which a control command is appended that commands the reduction of electrical power consumption. If it is data for printing to which a control command is appended, then the control unit does not execute any image forming operation, but instead stores this data for printing with control command appended in the storage unit.

Abstract: An image processing device includes: (a) an identification ID/gradation correction data storage section for storing the gradation correction data items which are for use in generating, from image data, a plurality of output image data items subjected to gradation correction, respectively; (b) a set preparing section for (i) generating the output image data items by carrying out the gradation correction with respect to the image data in accordance with the gradation correction data items respectively, and (ii) preparing, in accordance with the gradation correction data items stored in the identification ID/gradation correction data storage section, plural sets by rendering, to the output image data items, identification information for identifying the gradation correction data items used for the generation of the output image data items, respectively; and (c) a transmitting/receiving section for transmitting the plural sets to a common transmission destination of the image forming apparatuses, via a host commu

Abstract: An immediate printing type image forming apparatus is provided of which the warm-up time is sufficiently shortened without causing any trouble to occur in the execution of image reading processing and/or image forming processing. The image forming apparatus is configured to determine a time required to raise the current temperature of the surface of a heating roller in a fixing unit to a predetermined temperature and increase the duty ratio of a power waveform to be fed to each of a copy lamp and a motor driving a polygon mirror when the time required thus determined is shorter than each of a time required to increase the current light quantity of the copy lamp to a predetermined light quantity and a time required to raise the current rotational speed of the motor to a predetermined speed, thereby turning each of the copy lamp and the motor into respective predetermined condition before the elapse of the determined time required.

Abstract: An object of the invention is to provide a display device of an image forming apparatus capable of displaying information that the user wants to obtain in a visually easy-to-recognize manner. In a compound image forming apparatus provided with: one of original reading means for reading image information from an original, image receiving means for receiving image information from a terminal connected to a network and a line image receiving means for receiving image information from a telephone line; image forming means for forming an image based on the image information obtained by the means; and a display portion for displaying the condition of the apparatus, a display condition control portion is provided that changes the display condition of the display portion to a visually easy-to-recognize condition when the condition of the compound image forming apparatus is changed.

Abstract: When copying is automatically started using an automatic original document feeder, an automatic start operation is prohibited after an original document jam is eliminated. When copying operations are interrupted due to an original document jam during the copying operation, an automatic original document feeder is opened and a jammed original document is removed, and the automatic original document feeder is closed again and the original document jam is eliminated, in the case that there still is an original document remaining in the automatic original document feeder after the original document jam is eliminated. An automatic start prohibiting flag is turned on. Conversely, when there is no original document remaining in such a manner, the automatic start prohibiting flag is turned off.
