发明名称 IMAGE FORMING DEVICE
摘要 PURPOSE:To always obtain stable and fine transfer irrespective of environments and the size of a material to be transferred by controlling with constant current at the outer region of exposure that is outside of picture region. CONSTITUTION:A power source 4 controls with constant current avoiding an APC (light intensity correcting) region which corrects light intensity by scanning a laser 5. Since this current inflow into bright electric potential part of the APC region is interrupted, a plus memory does not remain on image carrier 1 and the base fogging of the picture caused by this memory can be interrupted. Thus, stable and fine transfer is always maintained irrespective of environments and the size of a material to be transferred and a fine picture can stably be obtained.
