Abstract

In an image forming apparatus, a dust collecting unit is disposed in the front side of image forming units. The dust collecting unit includes a dust collecting box and a fan. The dust collecting box is communicated with developer cases. The fan sucks air in the dust collecting box and discharges the air. The fan sucks air that has passed through a filter in the dust collecting box and discharges the air to an exhaust duct. The exhaust duct is disposed between a toner container and a fixing device and forms an air passage that extends in a front-rear direction to reach an opening portion provided in the rear side. The air is discharged to an outside of the apparatus from the opening portion.

Description

technical field [0001] The present invention relates to an image forming apparatus provided with a mechanism for sucking air from a toner storage portion of a developing unit to remove floating toner, and a toner collection container used in the image forming apparatus. Background technique [0002] In an image forming apparatus, the ambient temperature of the toner storage portion may be raised due to the influence of ambient air heated by the heating device. Toner is composed of resin. Therefore, when the temperature around the toner containing portion rises, the temperature of the toner increases accordingly, and the fluidity of the toner decreases. In addition, in order to make the toner adhere to the photosensitive drum, it is necessary to impart a charge to the toner, but an increase in temperature is a major factor that causes a decrease in the charge amount of the toner. When the fluidity and charge amount of the toner decrease, a sufficient amount of toner does no...
