英文摘要	PURPOSE:To complete a multiple number of beam output level decision processed with one beam output level decision sequence by simultaneously deciding each remaining beam output level interlocking in a same level direction along with one beam output level decision. CONSTITUTION:A beam output level deciding means is constituted from a transistor, a resistor, and operation amplifiers (8 to 19), etc., one arbitrary beam output level, PM is monitored, each beam outputting level against each remaining beam outputs PS and PL interlocking in the same level direction along with one beam output level decision against this beam output PM are simultaneously decided by current which is fixed from a resistance ratio, and a multiple number of beam output level decision processes are completed by one beam output level decision sequence. Further, the sequence which decides the beam output by the beam output level deciding means is carried out by a controller 27 which constitutes a control means, and the multiple number of beam output levels PS, PM, PL are set as target values during an image formation process. Thus, a multiple number of beam output levels can be decided at the same speed as when one beam emitting level is decided.
