Abstract: An image forming apparatus includes a communicator; a medium color input device; an image processor including a color image generator, an edge detector, and a corrector; and an image forming unit. The image processor performs a correction process that corrects first image data corresponding to a first color and second image data corresponding to a second color. The image processor performs the correction process by causing, based on medium color of the recording medium, a first edge of a first image that is in the first image data and a second edge of a second image that is in the second image data and initially correspond, to be distanced from each other. The image forming unit forms the first image and the second image in this order on the recording medium, based on the first image data and the second image data that are corrected by the image processor.

Abstract: An image forming apparatus includes an image processing part performing a correction process and an image forming part respectively forming first and second images on medium. At a boundary of the first and second images, these images have first and second edge portions. When a first image width of the first image data is narrower than a predetermined width, the first image width is defined as a length determined from one portion of the first edge portion, the image processing part performs the correction process by selectively moving one of the first and second edge portions based on a pixel value of the first image. The image processing part obtains a degree of blackness of the first image based on the pixel value. When the degree of blackness is higher than a predetermined value, the image processing part performs the correction process by moving the second edge portion.

Abstract: An image forming apparatus includes an image processor and an image forming unit. The image processor performs a correction process that corrects first image data corresponding to a first color and second image data corresponding to a second color. The image processor performs the correction process by causing, on the basis of a medium color of a recording medium, a first edge of a first image that is in the first image data and a second edge of a second image that is in the second image data to be away from each other. The second edge corresponds to the first edge. The image forming unit forms the first image and the second image in this order on the recording medium, on a basis of the first image data and the second image data that are corrected by the image processor.
