PURPOSE:To reduce variation of the recording density of a picture element to be recorded caused by the correlation between the picture element and the recording/non- recording of neighboring ones by providing a means to correct the laser exposure value for each picture element corresponding to the correlation between the each picture element and the neighboring ones. CONSTITUTION:The correcting means to correct the laser exposure value for each picture element corresponding to the correlation between the binary recording signal of each picture element and that of neighboring ones, is provided. For instance, a recording dot width correcting circuit 30 compares the binary recording information (data 1) of an attended picture element and the preceding and succeeding ones to each other. The circuit 30 extends the recording time of the attended picture element from Td to Tm only in case where the preceding one is non-recording, the attended one recording, and the succeeding one non-recording. In cases where the preceding one and the attended one are recording and where the preceding one and the attended one are recording and where the attended one and the succeeding one are so, the extension of the recording time of the attended picture element is not actually executed. In such a manner as the above, the recording-dot width correcting circuit 30 modifies the recording time of the attended picture element corresponding to the correlation between said element and the neighboring ones in the X-direction of main scanning.
