Abstract
A toner conveying device for an image forming apparatus includes a nozzle capable of penetrating into a toner container when the toner container is mounted to the image forming apparatus. The nozzle has a tubular structure forming an air passage for sending air into the toner container and a toner passage for delivering toner discharged from the toner container. Air sent into the toner container via the air passage fluidizes toner existing in the toner container, so that the toner can be surely replenished to a developing unit.
