A device for producing a picture such as a printer and a copying machine being capable of obtaining a high quality color picture at a low price. The device comprises a continuous photosensitive member (9) having microcapsules each containing a photosensitive material and a color material on a supporting body, an exposing device (7, 8...) for exposing the photosensitive member with light, a heat developing device (20) comprising a heating means (21) which is brought into contact with and separated from the photosensitive member, a pressure-transferring device (30) which pressing a transferring member (12) and the photosensitive member laid on the transferring member 12), and a carrying device for carrying the photosensitive member. The photosensitive member unexposed yet is prevented from suffering from heat by blocking heat. Also, the heat developing, pressure-transferring and carrying device are so configured respectively as to be changeable from a heating to a non-heating state, from a pressing to non-pressing state and from a forward to backward direction of carrying the photosensitive member, and vice versa. When producing a picture, the heat developing and pressure-transferring device are set to be in the heating and pressing states respectively and the photosensitive member is carried in the forward direction. When completing the producing of the picture, the heat developing and pressure-transferring device go to the non-heating and non-pressing states respectively and the photosensitive member is carried in the backward direction.
