A fundus imaging apparatus includes: an interference optical system configured to detect, with a detector, an interference state between a reference light and a measurement light that is reflected at a fundus; an optical scanner configured to scan the fundus with the measurement light; an optical member configured to adjust an optical path length difference between the measurement light and the reference light; an imaging unit configured to photograph a tomographic image of the fundus based on an output signal from the detector; a first optical path length adjuster configured to move the optical member, based on a light-receiving signal output from the detector corresponding to a position of the optical member; a second optical path length adjuster configured to readjust a position of the optical member; and an optical system adjuster configured to adjust the interference optical system between adjustments by the first and second optical path length adjusters.
