It is charged to a desired polarity by Ron 2. Next, the light emitting means of the optical writing device 3 is caused to selectively emit light based on both image signals, and the light is focused on the photoreceptor 1 by the SELFOC lens to form an electrostatic latent image. Thereafter, toner is applied to this electrostatic latent image by a developing device 4, and then this toner is transferred onto a recording paper 8 by a transfer corotron 5 and fixed by a fixing device 6. The photoreceptor is cleaned by a cleaning device 7 for the next operation.

Since we have provided a member that adsorbs or decomposes ozone near the JQ surface and/or the output end face, when an optical printer equipped with this optical writing device performs a blank operation, the ozone generated by a charge corotron, etc. will be removed. Near the end face of the Selfoc lens, ozone is adsorbed or decomposed by a member that adsorbs or decomposes ozone, and the ozone concentration decreases near the end face of the Selfoc lens. Therefore, the surface of the SELFOC lens is resistant to corrosion, and even after long-term printing operations, printed images of good quality can be obtained.
