PURPOSE: To decrease the calculation time in a mutitude of calculations in various conditions by calculating the surface electron charge accumulated on a induction body from the potential difference between the induction body surface and corona discharge wire. ;CONSTITUTION: By assuming the potential on a light sensor 7 at a certain value, an ion current density (ΔV-J) table is made. Then, by setting the initial surface charge on the light sensor 7 and considering the charge, the electric potential on the light sensor 7 is calculated from the potential distribution in the space including a charger and eliminator and in the region of the light sensor 7. Ion current density to each point on the light sensor is obtained by referring to the ΔV-J table from the potential difference ΔV between this potential and discharge wire 3 and surface charge on the light sensor 7 is calculated. And by solving a charge move equation corresponding to the moving velocity of the light sensor 7, the surface charge distribution on the light sensor 7 is calculated to obtain the potential on the light sensor 7. Thus, the calculation is continued till the required time and charge potential on the light sensor 7 is obtained.;COPYRIGHT: (C)1993,JPO&Japio
