Abstract
An image forming device including a photosensitive member, a development device and a thermal treating device is provided to form an image on a sheet of paper. The development device uses pressure rollers to develop the paper under pressure and includes a mechanism for varying the pressure. A movable shutter controls the amount of radiant heat provided by the thermal treatment device. When the power is turned off, the shutter closes to prevent further heating. The image forming device also includes a device for removing gases formed during the image forming process.
