Abstract

The invention relates to an image forming apparatus having an image forming unit, a fixing unit, a conveying unit including plural conveying paths, a cooling fan, an air duct including a first air-blowing outlet and a second air-blowing outlet for conducting air from the cooling fan to an interior of the apparatus, and an air flow changing member for opening or closing the first and second air-blowing outlets, wherein the recording sheet on the different conveying path is cooled by changing the air flow changing member. An image forming apparatus having, an image forming unit, a fixing unit, a conveying unit, a cooling fan for cooling the recording material on which the toner image is formed, and a restrict member for restricting a volume of drawing of air by the cooling fan.

Description

[0001] related application [0002] This application is based on Patent Application Nos. 2005-265179 and 2005-135026 filed in Japan, and therefore, the entire contents thereof are incorporated herein by reference. technical field [0003] The present invention relates to an image forming apparatus such as a copying machine, a printer, and a facsimile machine, and more particularly, to an image forming apparatus capable of printing data on one side of a recording material and also printing data on both sides of the recording material by turning the recording material over. to print the data. Background technique [0004] Most of recent image forming devices such as copiers, printers, and facsimiles are capable of printing image information not only on one side of a recording material (also called transfer paper or paper) but also on both sides of the recording material by electrophotography. Print image information on the screen. [0005] In some cases, such an image formin...
