No. 59-174833, No. 59-174834, No. 59-174835, etc.) An apparatus for implementing this type of image forming method is disclosed in, for example, Japanese Patent Laid-Open No. 59-75247. After exposing a color image to a heat-developable photosensitive material using an exposure head in an exposure section, the photothermographic material is coated with an image forming solvent such as water, and then sent to a heat-developable section.
An image recording apparatus has been proposed in which an image-receiving material is brought into close contact with a heat-developable photosensitive material after heat development, and the image is sent to a transfer section, where the image is thermally transferred to the image-receiving material.
