An image forming apparatus includes an image forming unit, an acquisition unit, and a controller. The image forming unit forms images of an output material set including multiple types of output materials. The acquisition unit acquires image information of the output material set transmitted from a terminal apparatus. The terminal apparatus provides an identifier for identifying the output material set to each of the multiple types of output materials included in the output material set and transmits image information of each of the multiple types of output materials. The controller controls, in a case where the image information of the multiple types of output materials for each output material set is ready, the image forming unit to form the images of the output material set.
