Abstract: 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.

Abstract: 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.
