  • Patent number: 8452203
    Abstract: In an image forming apparatus, exhaust fans of a ventilation device and an intake port of an air purifier are provided on side wall portions respectively that are opposite each other in a main casing of the image forming apparatus, and the exhaust fans of the ventilation device are provided in a location higher than the intake port of the air purifier. With this configuration, silicone that is discharged from the exhaust fans of the ventilation device is almost never suctioned into the intake port of the air purifier, such that almost none of this silicone adheres to a discharging electrode of the ion generator, and an ion generating efficiency of the ion generator can be maintained over a long period without dropping.

  • Patent number: 8351816
    Abstract: An ion generating unit comprises a duct, an ion generating device, a mounting plate and a fan. The duct is configured so as to have an air intake port at a first end and so as to have an exhaust port at a second end. The ion generating device is disposed inside the duct. The mounting plate is configured so as to serve to attach the duct to the housing. The mounting plate has an opening aperture communicating with the duct, and is configured so as to be attachable to the housing and so as to function as a part of the housing when it is attached to the housing.
