Patent number: 6825872Abstract: 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.Type: GrantFiled: January 11, 2002Date of Patent: November 30, 2004Assignee: Ricoh Company, Ltd.Inventor: Hisao Chikano
