Embodiment Construction

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings as appropriate. In addition, the embodiment described below is merely an example for embodying the present invention, and does not limit the technical scope of the present invention.

[0019] In addition, for convenience of description, the image forming apparatus 10 is set in a usable state ( figure 1 The vertical direction in the shown state) is defined as the up-down direction 6 . In addition, in the installation state, the front-rear direction 7 is defined so that the side surface on which the operation display unit 17 is installed is the front (front). In addition, the left-right direction 8 is defined with reference to the front of the image forming apparatus 10 in the installation state described above.

[0020] Such as figure 1 As shown, the image forming apparatus 10 is a so-called internal discharge type digital multifunction machine.

[0021] The image formi...

Abstract

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.

Description

technical field [0001] The present invention relates to an image forming apparatus including a blower for cooling a transfer belt. Background technique [0002] Image forming apparatuses such as copiers and printers that form an image on a sheet member by electrophotography are known. Such an image forming apparatus is equipped with various components that are heat generating sources. For example, the image forming apparatus includes a heating device for melting toner, a motor for driving a roller for conveying the sheet member, a motor for agitating the toner in the toner container, and a motor for using the toner. A motor that rotates the transfer belt or photosensitive drum, etc. When the toner container is affected by heat from these heat sources, the temperature of the toner inside the toner container rises, thereby reducing the fluidity of the toner. In order for the toner to adhere to the photosensitive drum, it is necessary to impart an electric charge to the tone...
