摘要： An image forming apparatus includes a printer body having a developing portion and a fixing portion therein, a plurality of sheet feeding rollers provided along a sheet discharge path successively and driven to discharge a sheet passing through the fixing portion to an upper portion of the printer body, and a rear cover provided on a side of the printer body to open and close, and having guide ribs to guide the sheet passed through the fixing portion. The image forming apparatus also includes an idle roller provided movably on the rear cover, to contact and rotate with one of the sheet feeding rollers to feed the sheet, and a supplementary guide member provided rotatably on the rear cover and positioned below the idle roller. The supplementary guide member changes a position thereof when the rear cover is open so that the sheet being discharged directly to the guide ribs is prevented from running into the idle roller.

摘要： A cooling apparatus of an electrophotographic image forming apparatus includes a cooling fan and a first opening. The cooling fan emits heat in the electrophotographic image forming apparatus to an outside of the electrophotographic image forming apparatus, is installed in any one of two frames that are opposite to each other so as to support a fusing unit, is disposed in a direction where a paper is discharged from the fusing unit, and allows internal air to flow out. The first opening is formed in a first frame that is opposite to a second frame in which the cooling fan is installed, and allows external air to flow into the electrophotographic image forming apparatus. The cooling apparatus is applied to a dry or wet electrophotographic image forming apparatus. The cooling apparatus emits heat generated from a fusing unit to the outside without affecting temperatures of a photosensitive drum and a developer unit so as to prolong a usable period of the photosensitive drum and improve an image quality. Also, waste toner is not congealed so as to reduce a load exerted on the cooling apparatus and the developer unit.
摘要翻译： 电子照相图像形成装置的冷却装置包括冷却风扇和第一开口。 冷却风扇将电子照相图像形成装置中的热量发射到电子照相图像形成装置的外部，安装在彼此相对的两个框架中的任何一个中，以支撑定影单元，沿着 纸从定影单元排出，并允许内部空气流出。 第一开口形成在与安装有冷却风扇的第二框架相对的第一框架中，并且允许外部空气流入电子照相图像形成装置。 将冷却装置应用于干燥或湿电子照相图像形成装置。 冷却装置将从定影单元产生的热量发射到外部，而不会影响感光鼓和显影剂单元的温度，以便延长感光鼓的可用周期并提高图像质量。 此外，废粉不凝结，以减少施加在冷却装置和显影剂单元上的负荷。
