Abstract:
1. An image forming apparatus comprising: an exposure portion having a light source, for forming a latent image on a photothermographic imaging material by exposing a light beam to the photothermographic imaging material from the light source; a thermal development portion having a heating portion for thermally developing the photothermographic imaging material on which the latent image is formed, by heating, and a cooling and conveying portion for conveying and cooling the thermally developed photothermociraphic imaging material; a temperature detecting member for detecting at least one of a temperature of a predetermined portion concerning the cooling and conveying portion and a temperature in a vicinity of the exposure portion; and a control unit for controlling a factor relating to thermal development on a basis of the temperature detected by the temperature detecting member, wherein the control unit makes an operation stop when the temperature detected by the temperature detecting member is outside of a predetermined range, and wherein the control unit makes the operation restart when a time that the operation is stopped exceeds a predetermined time.
