Abstract
An image forming apparatus includes an image forming device, a base, circuitry, and a detector. The image forming device includes a recording head to form an image on a recording medium conveyed in a conveyance direction. The base supports the recording medium and is movable in the conveyance direction. A type of the base is changeable according to a type of the recording medium. The circuitry sets a detection range in the conveyance direction. The detector detects, before the image is formed, a collision between the recording head and the recording medium on the base, in the detection range set by the circuitry.
