IPC: B41J2/44
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To improve image quality by controlling deflection by an optical polarlizer deflection based on differences of data synchronously with a scanning optical system, thereby preventing mutual position among plural optical beams from being fluctuated due to the temp. change and the secular change of an optical system in the preceding stage of a scanning optical system.

When a rewrite command α is outputted, a beam position for one light beam is detected with a beam detecting element 14 and data of the position is obtained and the difference is calculated. The difference is stored in a memory 44. Differences are calculated separately in the same manner with respective all light beam to be stored in the memory 44. Then, optical deflection elements AODs are driven so as to apply prescribed deflections to respective light beams and, however at this time, mutual positions among respective light beams are properly controlled by adding corrections to the elements based on the differences.  Thus, multiplexed beams in which the mutual positions are properly maintained are scanned with a common scanning optical system SP to scan on a recording sheet S.
