An image forming apparatus is provided which includes a printing device, an image orientation identification device, a medium orientation identification device, a conversion device, and a prohibition device. The printing device prints an image represented by image data onto a recording medium. The image orientation identification device identifies orientation of an image represented by the image data. The medium orientation identification device identifies orientation of the recording medium for use in printing by the printing device. The conversion device converts the image data, when there is inconsistency between the orientation of the image identified by the image orientation identification device and the orientation of the recording medium identified by the medium orientation identification device, such that the orientations of the image and the recording medium are consistent with each other. The prohibition device prohibits operation of the conversion device under a predetermined condition.
