In this paper we focused a second stage of transfer process in the intermediate transfer system and investigated the electrical properties of a transfer belt and a transfer medium based on a charge transport equation.We were able to demonstrate that the transfer belt had indeed an ohmic conduction regime and a space-charge limited current regime. The space-charge limited current regime itself characterizes a field independent carrier mobility regime and a field dependent carrier mobility regime. The field dependence of conductivity in the ohmic region can also be found in the transfer medium. The dielectric constant was calculated by a step response under observation of the field dependence of carrier mobility. As a result, the dielectric constant was constant values across the field for both the transfer belt and the transfer medium.The obtained parameters were then further applied to the second transfer process, in which the electric field distribution and the transfer efficiency were simulated.
