An image forming apparatus includes an image memory, an image receiving unit, an image determination unit, an image search unit, an image forming unit, and an image converter. The image memory stores replacement image data. The image receiving unit receives image data from the outside. The image determination unit determines whether the received-image data includes to-be-replaced image data. The image search unit searches, in a case where it is determined that the received-image data includes the to-be-replaced image data, the image memory for replacement image data corresponding to the to-be-replaced image data. The image forming unit forms an image. The image converter converts, in a case where the corresponding replacement image data is detected, the received-image data into to-be-output image data in which the to-be-replaced image data is replaced with the corresponding replacement image data, and causes an image based on the to-be-output image data to be formed.

An information processing apparatus includes a first acquiring unit, an identifying unit, and a transmitting unit. The first acquiring unit acquires image data including color values each of which denotes a corresponding one of multiple pixels in one or multiple pages. The identifying unit identifies, from the color values, color regions to which pixels constituting at least part of the multiple pixels belong in a predetermined color model. The transmitting unit transmits the number of pages in which the color regions identified by the identifying unit correspond to a predetermined color region combination.

A bi-color-image-signal generating apparatus includes a reception unit and a generating unit. The reception unit receives specification of a specified color in a case of generating a bi-color image signal from a color image signal. The bi-color image signal has color components representing two colors which are an achromatic color and a chromatic color that is the specified color. The generating unit obtains an amount of each color material which is to be used to form an image having the two colors from the color image signal on the basis of a brightness of the specified color, an amount of each color material which is necessary for image formation using the specified color, and a brightness of the color image signal, and generates the bi-color image signal from the color image signal using the obtained amount of each color material.

A line width measuring device includes an acquisition unit, an extraction unit, and a generation unit. The acquisition unit that acquires a binary image that is obtained by reading a medium having a line width sample printed thereon with an image reading device, the line width sample representing output characteristics regarding a line width of an image forming device. The extraction unit that extracts a displacement amount of steps that are repeatedly generated in an image corresponding to the line width sample in the binary image by reading the medium with the image reading device in an orientation such that the line width sample has an angle &#x3b8; (0&#xb0;&#x3c;&#x3b8;&#x3c;90&#xb0;) with respect to a main scanning direction of image reading. The generation unit that generates line width information regarding a width of the line width sample by using the displacement amount extracted by the extraction unit.

An image processing apparatus includes a storage unit, a judgment unit and a conversion unit. The storage unit stores a reference color characteristic. The judgment unit judges as to whether or not a difference between an input color characteristic that is a color characteristic of input image data and the reference color characteristic is equal to or less than a predetermined threshold value. The conversion unit converts the input image data into a color characteristic that can be reproduced by an image reproducing apparatus, based on the reference color characteristic if the difference is equal to or less than the predetermined threshold value.

An image forming control apparatus includes: a gradation correction curve generator and a calibration data generator. The gradation correction curve generator generates a gradation correction curve based on a correspondence between an output instruction values each representing a density of an image to be formed by an image forming apparatus and actual density values each representing a density of the image formed by the image forming apparatus. The gradation correction curve represents a correspondence between predetermined standard density values and the output instruction values. When an output instruction value corresponding to a maximum standard density value is smaller than a maximum output instruction value, the calibration data generator corrects the gradation correction curve so that the output instruction value corresponding to the maximum standard density value coincides with the maximum output instruction value, and generates the calibration data based on the corrected gradation correction curve.
