Image forming apparatus having air blower for cooling

摘要

An image forming apparatus includes a transfer portion, a fixing portion, a container mounting portion, an air blower, and an air duct portion. The transfer portion has a transfer belt extending in a first direction. The fixing portion is provided on one side in the first direction with respect to the transfer portion. The container mounting portion is provided so as to be spaced via a first air passage having a predetermined interval in a second direction perpendicular to the transfer belt and perpendicular to the first direction. In the container mounting portion, one or a plurality of toner containers containing a developer are mounted. The air blower is provided on another side in the first direction with respect to the container mounting portion, and configured to send air to the first air passage. The air duct portion guides air sent from the air blower, to the first air passage.

1. An image forming apparatus comprising:
a transfer portion having a transfer belt extending in a predetermined first direction; a fixing portion provided on one side in the first direction with respect to the transfer portion; a container mounting portion which is provided so as to be spaced via a first air passage having a predetermined interval in a second direction perpendicular to the transfer belt and perpendicular to the first direction, and in which one or a plurality of toner containers containing a developer are mounted; an air blower provided on another side in the first direction with respect to the container mounting portion, and configured to send air to the first air passage; and an air duct portion provided between the air blower and the container mounting portion and configured to guide air sent from the air blower, to the first air passage, wherein
the air duct portion is capable of supporting a side surface of the toner container,the air duct portion is a guide portion configured to support a side surface on the other side of the toner container so as to allow the side surface to be guided in a third direction perpendicular to the first direction and the second direction,the guide portion is formed in a box shape having a space therein,a side surface on the other side of the guide portion has a first opening,the air blower is attached to the side surface of the guide portion such that an air inlet of the air blower is directed to the other side and an air outlet of the air blower is directed to the first opening side,the guide portion has, in a bottom surface thereof, a second opening through which air flowing inside the guide portion from the first opening is blown obliquely downward, andthe second opening is formed at a corner between the bottom surface and a side surface on the one side of the guide portion.
