An image recording device mounted on an electro-developing type camera using an electro-developing recording medium in which an object image obtained through a photographing optical system is electronically developed. The electro-developing recording medium has a first recording area in which the image is recorded, and a second recording area in which information other than the image is recorded. First and second electrodes are provided in the first and second recording areas, respectively, so that an electric voltage can be independently applied to the first and second recording areas. By exposing the first recording area while applying the voltage thereto, the image is recorded in the first recording area. By heating the second recording area without applying the voltage thereto, the information is recorded in the second recording area.
