Abstract

An image forming apparatus includes a head, a detector, and circuitry. The head forms an image on a recording medium. The detector detects a vertical movement of the recording medium and a distance to the recording medium in a vertical direction. The detector includes an optical sensor to project light to the recording medium and receive the light reflected from the recording medium. The circuitry sets a first area based on a result of detection performed by the detector. The first area is an area in which the recording medium and the head collide with each other. The circuitry retracts the head to prevent the recording medium and the head from colliding with each other, in a case where a position of the head is in the first area.
