PURPOSE:To provide an image forming device capable of recognizing the remaining quantity of a photosensitive recording medium. CONSTITUTION:A constant voltage is impressed between the leading edge and the trailing edge of a microcapsule paper 37 by a power supply E, and the voltage at the leading edge point of an unexposed part is measured by a voltage measuring pin 58. And the number of remaining sheets on which exposure can be performed is calculated based on the ratio of a measured voltage value to a constant voltage value, and the calculated number of the remaining sheets is displayed on a keyboard 60. |
