Image forming apparatus

An image forming apparatus configured to form a plurality of toner images by using toner of a plurality of colors and superimpose the plurality of toner images to perform printing on a recording material, the plurality of toners including a first toner, a second toner, and a third toner of different colors,

• the image forming apparatus comprising:
• an image forming unit configured to form a first toner image using the first toner, a second toner image using the second toner, and a third toner image using the third toner;
• a transfer unit for transferring in a superimposed manner onto the recording material the first toner image, the second toner image, and the third toner image in this order, which is an order closer to the recording material;
• and
• a fixing unit having a heating unit for heating the recording material from a side where the toner image is transferred, the fixing unit being configured to heat and melt the toner image by the heating unit and fix the toner image onto the recording material,
• wherein, among the first toner, the second toner, and the third toner, the first toner has a highest elastic modulus, and the second toner has a lowest elastic modulus,
• the color of the first toner is black, and
• when forming a black image, single-color black using only the first toner and process black using all the plurality of toners are selectable.
