An image forming apparatus includes a processor that derives, for each of a plurality of blocks of image data, a value indicating a toner amount to be used in forming a toner image by referring to a density of every pixel, of a plurality of pixels included in each block of image data, shifts a window, and outputs the window before shifting and the window after shifting, the window before shifting and the window after shifting overlapping with each other, and determines a fixing temperature for a fixing operation based on an analysis result of a first toner amount in the window that is output by referring to the toner amount of each block included in the window before shifting, and an analysis result of a second toner amount in the window that is output by referring to the toner amount of each block included in the window after shifting.

Provided are an image forming apparatus for outputting a plurality of images having different sizes according to a method pre-set by a user without interrupting a current printing operation when the plurality of images having different sizes are obtained and a method of operating the image forming apparatus.

An image forming apparatus includes an image forming unit that forms an image on a recording medium according to image data, and an adjusting unit that adjusts the image around a cut when the recording medium has the cut.

An image forming apparatus of the present invention includes: a determination unit that determines toner application amounts based on image data; a memory device that stores a set of instructions; and at least one processor that executes the set of instructions to: control fixing temperature for fixing a toner image formed from the image data to a printing medium in accordance with information created for each printing page by analyzing the determined toner application amounts; and fix the toner image to a printing medium at the controlled fixing temperature. The determination unit divides each printing page of the image data into a plurality of meshes of a predetermined size and determines positions corresponding to the meshes obtained by the dividing, and counts the toner application amounts of pixels in each of the meshes based on a determination result of the determining of the positions and the image data.

A nail production system according to an embodiment of the disclosure includes a first correction section and a first conversion section. The first correction section corrects shape data of an existing nail tip or an existing nail sticker on the basis of measurement data of a nail, to thereby generate shape data of an original nail tip or an original nail sticker. The first conversion section converts the shape data of the original nail tip or the original nail sticker that is generated by the first correction section into print data.

An image forming apparatus includes a reading configured to read a shape of a sheet to be used for image formation, and an original sheet carrying an original image, and an image forming portion configured to form a toner image, corresponding to the original image read by the reading portion, on the sheet to be used for image formation. A fixing portion is configured to fix the toner image, formed by the image forming portion, to the sheet to be used for image formation. In addition, a controller is configured to control a fixing condition of the fixing portion in accordance with the shape of the sheet to be used for image formation read by the reading portion.

An image processing apparatus includes an image acquiring portion, a pair generating portion, first through third determination portions, and an image combining portion. The image acquiring portion acquires an image for each page of a booklet. The pair generating portion arranges the images in order of the pages of the booklet, and generates pairs from the arranged images, each pair being a pair of adjacent pages in a spread state of the booklet. The first determination portion determines whether a drawn image is present in a band-like region including a boundary between two images in each of the pairs. The second determination portion determines whether there is drawing continuity between the two images. The third determination portion determines whether the two images have to be combined, on the basis of determination results of the first and second determination portions. If so, the image combining portion combines the two images.

A printing apparatus having a copying function includes a document feeder that feeds a document, an image reading section that scans the document fed from the document feeder and generates image data of the document, a printing section that performs printing on paper in accordance with the image data, and a controller. The controller performs an avoidance process of avoiding performing the printing in which a size of a sheet of the document and a size of the paper do not match against an intention of a user, in a case where a setting is made in which the document, on which single-sided printing is performed, is printed on both sides of the paper to perform double-sided printing, and the document includes sheets having different sizes and includes an odd number of successive sheets with an identical size.

An image forming apparatus includes an image forming unit that forms an image on a recording medium according to image data, and an adjusting unit that adjusts the image around a cut when the recording medium has the cut.

An image forming apparatus includes a reading section and an image forming section. The reading section reads a plurality of images from a document. The image forming section forms the plurality of read images on a sheet. The plurality of images include a first image and a second image. The first image has a first color. The second image has a second color. The second color is different from the first color. The image forming section forms the first image on a first main side of the sheet and the second image on a second main side of the sheet.
