  • Patent number: 6825872
    Abstract: An image forming apparatus having a ventilating device that can effectively cool heated components and remove ozone produced in the apparatus. The image forming apparatus includes a writing device. Upper and lower ducts are provided to the writing device having a housing of the writing device therebetween to form an outside-air flowing path on and beneath the writing device. Outside-air intaken by an air intake fan flows through the upper and lower ducts separately. In the writing device, scanning optical components, such as an f&thgr; lens, and a mirror formed of a plastic are disposed.

  • Patent number: 6792226
    Abstract: In an image forming apparatus including a cooling device that efficiently cools an inside of a main body of the image forming apparatus, the cooling device has an airflow path in which air taken in the main body of the image forming apparatus flows through a drum-shaped image carrier from a first end side of the image carrier, flows through the image carrier, and is discharged from a second end side of the image carrier, then makes a U-turn on the second end side of the image carrier, and flows through space between a toner storing device and a fixing device, and returns to a position on the first end side of the image carrier in the main body of the image forming apparatus. A fan may be provided at a position where the air makes a U-turn in the airflow path.

  • Patent number: 5255060
    Abstract: A heat roller type fixing apparatus which prevents forming of wrinkles on a material for printing and eliminates a jitter of a picture. The apparatus comprises a single fixing roller equipped with a heater, and two pressing rollers pressed to the fixing roller. The fixing roller and the two pressing rollers are arranged so that a collision angle, an angle in which the printing material ejected from a nip portion of a first pressing roller collides with a second pressing roller, is less than 67 degrees.
