ABSTRACT:
The image recording device includes a paper feed device for feeding a recording paper, a photosensitive body, a toner feeding unit, a module for forming a toner image on the photosensitive body, and a transferring roller. The photosensitive body is opposed to the transferring roller such that the recording paper fed from the paper feed unit is nipped between the photosensitive body and the transferring roller. The image recording device also includes a voltage generator for generating a voltage to be applied to the transferring roller. The voltage to be generated by the voltage generator is adjusted such that transfer of the toner image onto the paper is properly carried out. The collective resistance of the transfer roller and photosensitive body is detected and the voltage generated by the voltage generator is adjusted accordingly.
