<p>An image formation apparatus using a photosensitive member having heat developability, in which process control is performed over a period from heat development to pressure transfer to form an image under a stable condition without effects of ambient temperature and the condition of use of the apparatus. To this end, it is very effective to detect temperature and humidity during a period from heat development to pressure transfer, and to control the temperature and heating time for heat development or to stabilize the temperature of the photosensitive member after heat development till pressure transfer, and particularly to make cooling below a predetermined temperature. It is preferred, as the cooling method, (1) to make cooling below a temperature which is 50 °C higher than pressure transfer temperature, and (2) to start cooling within 10 seconds after completion of heat development. As a specific cooling mechanism, preferred is an air cooling method using cooling rollers (59, 74), fans (60, 63, 72), etc. Alternatively, a water cooling method using a cooling roller (76) may be employed.</p> |
