In this research the Fourier transform of electric field in a three-layered model with thickness t_j and dielectric e_rj  is computed, after solving three dimensional Laplace equation for Fourier transform of potential under suitable boundary conditions.Then, by studying the behavior of spread function, a three-layered photoreceptor is designed. After designing and constructing of all of the subsystems, the depostion of Al and formation of Al₂O₃ are carried out at 2´10^-5 to 5´10^-7 mbar pressure. Then coating of Se is carried out under 2´10^-7  mbar pressure, 250 °C boat temperature and 95°C substrate temperature in 120 min. Electrical resistance of the prepared sample was measured to be higher than 10¹² W in dark and about zero in than light, this values are suitable for making electrostatic latent image. To test its function in practice, the sample was mounted in Xerox machine and images were copied successfully.
