Abstract
An image forming apparatus includes an unfixed-image forming unit for forming an unfixed image having a plurality of colors on a recording material, and a fixing unit for fixing the unfixed image formed by the unfixed-image forming unit by heating the recording material bearing the image. The fixing unit can fix the unfixed image on the recording material with a first degree of fixing or with a second degree of fixing which is greater than the first degree of fixing depending on whether or not a light-transmitting-property recognition unit recognizes the recording material to have a light-transmitting property, and whether or not a black-monocolor recognition unit recognizes the unfixed image formed by the unfixed-image forming unit as a black monochromatic image. When the image forming apparatus recognizes that the recording material has a light-transmitting property and that the unfixed image is a black monochromatic image, the fixing unit can fix the unfixed image with the first degree of fixing or with the second degree of fixing based on information relating to an image formed by the fixing unit.
