PURPOSE:To lower ozone concentration in exhaust and to suppress the rising of temperature in the title device by forming plural air conducting paths opposed to a suction means for exhausting air in the device to the outside, making one of the air conducting paths connect to a corona discharger through an air path and providing a filter means on the air path. CONSTITUTION:The air whose ozone concentration is high around a primary electrostatic charger 4 and a pre-exposing device 10 which is the corona discharger is sucked by a fan 14 which becomes the suction means and passes through a pre-exposing window 13 as illustrated by an arrow (a). Then it flows in a main body duct 16 constituting the air path in parallel with the window 13, is conducted a guide duct 18 and exhausted to the outside of the device through an ozone filter 17. The fan 14 not only exhausts the air containing ozone from a cartridge K but also performs the function of discharging heat of a power source 15 and a fixation device 8, etc. Thus, the ozone concentration of the air exhausted to the outside of the device can be lowered and the rising of temperature is suppressed. |
