Abstract

PURPOSE:To improve ozone removing efficiency, to prevent rise of temp. due to radiation heat from exposing light source, and to increase the mounting density of a reproducing device by elevating the temp. of an ozone removing agent by the heat generated by the exposing light source by coating the ozone removing agent on a reflecting mirror member. CONSTITUTION:In an electrostatic recording device, a liquid ozone removing agent 5, 17 comprising a mixture consisting of powdery metal oxide such as MnO2 or PbO2 and a binder is coated on a part of elliptic reflecting mirrors 2, 16 having foci at the centers of exposing halogen lamps 1, 15, not contributing to the reflection of light. The temp. of the reflecting mirrors 2, 16 are elevated by the radiation heat generated by the halogen lamps 1, 15 during operation of the electrostatic recording device, and the temp. of the ozone removing agent 5, 17 are elevated thereby. The ozone generated during operation of corona dischargers 6, 10, 11 is sucked by a fan 19 and is allowed to contact with the ozone removing agent 17 having increased ozone removing efficiency by the temp. rise to perform removal of ozone.

Conventional Structures and Their Problems In recent years, many small, low-cost copying machines have used organic photoconductors for photoreceptors in view of their cost and ease of manufacture. When using an organic photoconductor, the surface of the photoreceptor must be negatively charged in most cases. That is, it is necessary to apply a negative voltage to the corona discharger.

This time order is the generation of ozone due to inelastic collisions between charged particles accelerated in a discharge field and oxygen molecules. Ozone is generated even when a positive voltage is applied to the corona discharger, but
The voltage is about one-seventh that of a negative voltage, so it hardly poses a problem.

This ozone is harmful to the human body, so it is becoming compulsory to remove it.For example, if it is used continuously indoors at a certain capacity, the equipment will be removed! The situation has become such that the ozone concentration at a location 1130 crn away is less than 0.1 ppm. Generally, when a corona discharger is used to remove generated ozone, it is necessary to increase the contact time between the ozone and the ozone remover in order to effectively remove the ozone.
