Image forming apparatus

An image forming apparatus comprising:

• an image input device that receives an input of image data;
• an image forming device that forms an image on a recording medium;
• a supply device including a plurality of cassettes, and configured to deliver the recording medium stored in the plurality of cassettes to the image forming device;
• a detection device that detects a color of the recording medium stored in the plurality of cassettes;
• and
• a control device including a processor, and configured to act, when the processor executes a control program, as a controller that:
• classifies, when the image data representing a plurality of cut patterns each having a color is inputted through the image input device, the plurality of cut patterns by putting the cut patterns having a color of a same family in a same group, according to predetermined classification information indicating a plurality of colors classified by color family;
• places the groups each including the plurality of cut patterns classified, on different pages;
• generates a cutting line representing a contour of each of the plurality of cut patterns placed;
• selects the cassette, from which a color of the recording medium, of the color family that accords with the color family of the cut patterns placed, has been detected by the detection device, with respect to each of the pages;
• causes the supply device to supply the recording medium from the selected cassette, with respect to each of the pages;
• and
• causes the image forming device to form the generated cutting line on the recording medium, with respect to each of the pages.
