An image processing apparatus includes a receiving unit that receives a display request for displaying a preview image of gradation-processed image data, and a preview magnification indicative of a display magnification of the preview image. An image processing unit performs a first magnification-altering process on the gradation-processed image data performs the gradation process based on the image quality mode if the preview magnification is lower than a present magnification and the gradation process based on the image quality mode is such that the gradation-processed image data does not express halftone, as well as if the preview magnification is higher than the present magnification thereby obtaining processed image data. A display unit creates and displays the preview image based on the processed image data.
