An electrophotographic image formation device comprises an image transfer unit (including an image transfer member) attached to a main body in a detachable manner, a density detecting unit including a detector unit and thereby detecting density of a developing agent transferred to the image transfer member, a protective cover which protects the density detecting unit not detecting the density by covering the detector unit, first and second reflecting parts (differing in reflectivity) formed in a part of the protective cover facing the detector unit, and a shifting unit which places the protective cover at a first position (with the first reflecting part facing the detector unit) when the image transfer unit has been attached to the main body while placing the protective cover at a second position (with the second reflecting part facing the detector unit) when the image transfer unit has not been attached to the main body.
