Abstract
In a pressure developing device employed in an imaging device like a duplicating machine, an optical printer etc, pressure force for pressurizing a recording medium is capable of being varied in accordance with the width of the recording medium to be pressurized. A sensor for detecting the width of the recording medium is provided, and the pressure force is varied based upon the detected value.
