Abstract

A control device for image forming equipment capable of reducing ozone ascribable to an image forming process and detecting failures of the equipment caused by the ozone. Mists are produced from a liquid developer which is a toner-dispersed carrier liquid containing silicone oil during developing, image transferring and fixing steps. The mists and the ozone are discharged to the outside of the equipment by a fan. A filter liquifies the mists and ozone by mixing them together. Errors are detected on the basis of ozone concentration which is sensed by an ozone concentration sensor.
