Claims

[Scope of Claim for Utility Model Registration] In a recording device that charges a photoreceptor, exposes it to light, develops it, and transfers and fixes the developed image onto recording paper: A conveyance unit disposed at the bottom of a conveyance unit that sends the transferred recording paper to a fixing device. A fan that sucks air from the area; A filter for eliminating _O3 disposed at the bottom of the fan; and During the recording process, the motor that drives the fan is energized to rotate at high speed, and after the recording process, while the device is powered on. An electrophotographic recording device comprising: a motor energizing circuit that energizes low-speed rotation;
