Image forming apparatus

摘要

An intake fan (62) is provided on a side surface of an exposure device (40) provided below a plurality of image formation portions (20) far from a fixing unit (30), and a ventilation path (70) is formed on a side surface of the exposure device (40) on a back side, and outside air sucked by the intake fan (62) into a body of an apparatus is fed through the ventilation path (70) to the back side of the image formation portion (20K) closest to the fixing unit (30). The air flows through a space between a division plate (80) and the image formation portions (20) toward a discharge fan (61), and the image formation portions (20) are air-cooled sequentially from the image formation portion (20K). Thus, it is possible to effectively air-cool the image formation portions without increasing the size of the apparatus.

主权项

1. An image forming apparatus comprising:
a plurality of image formation portions that include: a rotatable electrostatic latent image carrying member; a charging unit which uniformly charges a surface of the electrostatic latent image carrying member; and a development unit which visualizes, with toner, an latent image formed on the electrostatic latent image carrying member and that forms toner images of different colors; a transfer unit that transfers the toner images formed and superimposed by the image formation portions to a transfer-receiving member; a fixing unit that heats the transferred toner images to melt and fix the toner images to the transfer-receiving member; and a blower system that forms an airflow moving from an image formation portion closest to the fixing unit to an image formation portion farthest from the fixing unit, wherein the image formation portions are air-cooled sequentially from the image formation portion closest to the fixing unit, and wherein the blower system is formed with an intake fan and a discharge fan, and outside air sucked by the intake fan into a body of the apparatus is fed to the image formation portion closest to the fixing unit.
