An image forming device for forming optically inputted two-dimensional images. A light valve, including a bistable electrooptic medium and a photoconductive material, acts as an image recording device which records an image inputted from an image inputting device. When the light valve is irradiated by the light from the image inputting device, the electrooptic medium makes a state transition by photoelectric converting action of the photoconductive material. The state of the electrooptic medium is dependent on the threshold voltage across the light valve and on the threshold intensity of the input light. The recorded image can be outputted to film or any type of visual display apparatus. The image inputting device can be a modulated scanned light beam, as from a laser.
