An image forming apparatus includes the following elements. An image data reading unit reads image data stored in a storage medium. An image forming unit forms an image on a recording medium on the basis of the read image data. A billing information generating unit charges a fee for the number of formed images. A test-indication adding unit adds test-indication data indicating a test image to the read image data. A test-print production instructing units instructs the image forming unit to form a test image on the basis of the image data with the test-indication data being added thereto. The billing information generating unit is configured to charge no fee when a test image is formed in response to an instruction provided by the test-print production instructing unit.
