PROBLEM TO BE SOLVED: To suppress the outflow of a harmful material produce from the inside of a printer body to the outside by surrounding an engine unit with a shielding cell so as to store gas carrier evaporated by a drying part and filtering air exhausted by a ventilating fan from the inside of the shielding cell. SOLUTION: The shielding cell 100 surrounds a photoreceptive belt 11, a developing unit 30, a transfer roller 50 and a fixing roller 60 so as to enclose and store the harmful material produced from the engine unit, for instance, the gas carrier produced by the drying part 70 inside. The ventilating fan 130 exhausting the air inside of the shielding cell 100 and maintaining the inside to be always in a low-pressure state is installed on the lower side surface of a printer body 200, and is provided with a filter 120 filtering the harmful substance at the flow passage of the air exhausted. The inside of the shielding cell 100 is set to be in the low-pressure state and inside air does not flow out to the outside in the operation of the ventilating fan 130, so that the air exhausted by the ventilating fan 130 is filtered by the filter 120. |
