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.
