| 英文摘要 | PURPOSE:To obtain image density free from fog, by adjusting a drive current value so as to obtain standard quantity of laser beam and subsequently applying limited fine control to a drive current on the basis of density indication. CONSTITUTION:A drive current is adjusted by a variable resistor 14 so as to obtain standard quantity PA of laser beam from semiconductive laser 1 By this method, standard image density based on a drive current (ia) is obtained. A variable resistor 15 allows the drive current applied to the semiconductor laser 11 to increase and decrease within a range, wherein an upper limit is set to a drive current ib and a lower limit to a drive current ic on the basis of the drive current ia, on the basis of density indication. Therefore, image density can be made variable under a proper fog state and a good image can be formed. |
