An image processing device that transmits print image data to an image forming portion to form a target image on at least one recording medium, includes a processor and a non-transitory, computer-readable medium storing computer-readable instructions that, when executed by the processor, cause the image processing device to perform steps including: generating display image data at a display scale for displaying the target image including an element of the target image on a display portion prior to formation of the target image on the at least one recording medium; and generating print image data at a print scale for forming the target image on the recording medium, such that the element of the target image to be formed on the at least one recording medium has substantially the same size as the element of the target image displayed on the display portion.
