摘要： An image forming apparatus includes a high-speed duplex-printing mode execution unit, a print request unit, an output processing unit, a request control unit, and a request invalidation unit. The high-speed duplex-printing mode execution unit executes a high-speed duplex-printing mode in which image formation is sequentially performed on first sides from a leading sheet, and then image formation is performed on a second side of at least the leading sheet. The print request unit issues simplex-printing requests. The output processing unit receives the requests, performs an output process, and causes image formation to be performed. The request control unit causes the print request unit to issue simplex-printing requests using, as a trigger, either input of each duplex-printing request or completion of the output process. The request invalidation unit maintains a trigger based on the output process completion as invalid.

摘要： An image forming apparatus continuously performs primary paper feeding in which paper is transported from a paper feeding roller to a resist position roller and secondary paper feeding in which the paper is transported from the resist position roller to an ejection roller while not stopping the resist position roller. The image forming apparatus divides image data into pieces of band data, stores the pieces of band data, calculates the number of specific bands corresponding to an in-advance paper feeding timing corresponding to the paper size and the paper orientation, and outputs an in-advance paper feeding timing notice when image process is completed up to the number of specific bands.

摘要： An image forming apparatus converts image data into a video signal, updates a value of a counter without loading the image data onto a video memory, if a print request is a single-sided print request and the image data corresponding to a page information included in the print request is stored on the video memory, and loads the image data corresponding to the page information in the print request onto the video memory, if the print request is a double-sided print request, or if the print request is the single-sided print request and the image data corresponding to the page information included in the print request is not stored on the video memory.

摘要： An image forming apparatus includes a print engine, a sheet transportation unit, an optical sensor, and an image processing unit. The print engine is configured to physically print an image to be printed on a print sheet. The sheet transportation unit is configured to transport the print sheet along a predetermined transportation path. The optical sensor is arranged so as to face the transportation path, and configured to detect a color of a test chart on a colored print sheet transported along the transportation path. The image processing unit is configured to perform color correction of the image to be printed on the colored print sheet, on the basis of the detected color of the test chart on the colored print sheet so as to restrain color change of the image due to a surface color of the colored print sheet.

摘要： A processor causes, when the number of initial insertion sheets is one or more, an insertion conveying portion and a takeover conveying portion to operate at either one of a conveying speed that is the same as a print conveying speed corresponding to a first recording sheet and a reference conveying speed according to a magnitude relationship between the number of initial insertion sheets and an initial sheet count in conveyance of the initial insertion sheets. In addition, the processor causes a body conveying portion and the takeover conveying portion to operate at the corresponding print conveying speed in conveyance of the recording sheet irrespective of the number of initial insertion sheets.
