Abstract

PURPOSE: To reduce an influence of edge effect by periodically interrupting a picture signal regarding the part where toner sticks and by changing its periodic phase according to every scanning line.
CONSTITUTION: A picture signal generated by recording signal generation part 1 is converted by shift register 2 from parallel to series and signal B on signal line SL1 is interrupted by AND gate 9 with output signal C on output signal line SL2 of masking signal generating circuit 10, so that the signal shown in fig. D can be obtained on signal line SL3. Then, fig. A shows a picture transfer clock signal. Since a masking signal is inverted in phase every time that a light beam from scanner 4 scans one scanning line on drum 6, a pitch-dark picture is recorded as a picture consisting of alternate picture elements arrayed zigzag as shown in the figure.
