In the conventional toner save processing, in the case where the color of each element, such as a character, a graphics, and an image, constituting an image is a pale color or bright color, visual recognizability will be degraded even by maintaining the density of an edge portion of each element. An image processing apparatus that performs color material save processing to perform color printing while suppressing a color material consumption compared to that at the time of normal printing, includes an edge detection unit configured to detect an edge pixel constituting an edge of an object within input image data, and a density adjustment unit configured to convert the color of a detected edge pixel into an achromatic color and to decrease the density of the color of a non-edge pixel, which is a pixel other than the edge pixel of the object.

An image forming apparatus includes an image forming section and a transfer section. The image forming section includes a first image forming unit that forms a first developer image and a second image forming unit that forms a second developer image. The transfer section transfers, on a basis of a first transfer condition, the first developer image onto a medium, and transfers, on a basis of a second transfer condition, the second developer image onto the medium onto which the first developer image has been transferred. The second transfer condition is different from the first transfer condition.

An information processing apparatus includes a first control unit configured to control an operation to be performed by the information processing apparatus and a second control unit configured to control an operation of an operation unit equipped with a display device. The first control unit generates first graphic data corresponding to a screen to be displayed by the display device. The second control unit generates second graphic data corresponding to a software key. Further, the information processing apparatus combines the first graphic data with the second graphic data to form composite graphic data and causes the display device to display the composite graphic data.

An image forming apparatus includes an image forming device which forms an image on a recording medium and an image scanning device which transmits scanned image data to the image forming device. The image forming device includes a receiver, a first image forming unit, a second image forming unit, and a controller. The receiver receives at least one of external image data transmitted from an external device and the scanned image data as input image data. The first image forming unit forms a developer image based on the input image data on the recording medium. The second image forming unit forms a mark image on the recording medium. The controller determines whether to make the second image forming unit form the mark image or not depending on a type of a transmission source of the input image data.

An image forming apparatus includes a first image forming section capable of forming a brilliant developer image, a second image forming section including at least one image forming section capable of forming a black developer image, a transfer section capable of transferring the brilliant developer image and the black developer image onto a medium, and a controller that controls operation of the first image forming section and the second image forming section according to received print data. When forming a brilliant image based on the print data, the controller performs control to form the brilliant image in which relative position between the brilliant developer image and the black developer image is changed depending on a medium type.

According to an embodiment, an image processing system includes an image forming unit, a decoloring unit, a storage device, an operation panel and a processor. The storage device stores image data of a plurality of printed materials. The processor forms on a sheet an image based on image data in a page range of the printed material received by the operation panel. The processor determines whether or not images of all pages in the page range have been decolored in a predetermined range after the image formation is executed when the formed image is decolored by the decoloring unit.

An image display device includes a command receiving unit that receives a command to display one page and a display control unit that displays a composite image on the indicated one page and a list of a plurality of image groups associated with the plurality of pages on a display unit at the same time. The display control unit distinctively displays two or more image groups among the plurality of image groups in the list and preferentially displays an image group associated with the one page in the list.

When trial printing is executed in a repeat printing mode, trial printing is performed in size of an image of one piece in a layout in which a plurality of images are supposed to be printed in the repeat printing mode normally. A user who has checked a finished state of the trial printing sets, when the finished state is in a desired state, the recording paper on which the trial printing is performed to the paper feed portion again and executes the repeat printing. Thereby, in a blank space excluding a print image which is printed with a first time trial printing, a scheduled quantity of a plurality of images are repeatedly printed.
