ABSTRACT:
An image forming apparatus has a water content determination apparatus that can precisely determining a water content in a medium regardless of an environment where the image forming apparatus is installed. The water content determination apparatus has a detection device that outputs a first signal while the medium is absent in an electrostatic capacitance region formed in a path where the medium is conveyed and outputs a second signal while the medium is present in the electrostatic capacitance region. The temperature in the image forming apparatus is determined based on the first signal. The water content in the medium is determined based on the second signal and the temperature determined by the temperature determination device.
