ABSTRACT:
An image forming apparatus for performing an exposure process of exposing a microcapsule sheet to light and performing a pressure-developing process of contacting the microcapsule sheet having the latent image thereon with a developer sheet under pressure, thereby to form a visible image on the developer sheet, comprises plural sheet feed rollers for feeding the microcapsule sheet from the sheet feed-out side of the microcapsule sheet to and along a sheet feed path and winding up the microcapsule sheet to thereby perform a sheet feeding operation, an optical sensor or lever sensor provided in the neighboring of the sheet feed-out side of the microcapsule sheet for detecting a sheet feeding condition, such as a residue of the microcapsule sheet, a sheet feed error, a sheet feed speed and so on in the sheet feeding operation and outputting a detection signal indicative of a detection result and a control unit for beforehand storing distance data on the sheet feed path of the latent image forming medium between the sensor and a pressure-developing unit and/or storing data on a sheet feeding condition of the microcapsule sheet based on the detection signal.
