摘要

A toner conveying unit includes a toner case, an intermediate unit, and a developing unit. The intermediate unit removably supports the toner case. The intermediate unit includes a toner inlet, a toner outlet, a toner conveying path and a shutter. The toner outlet discharges the toner received from the toner inlet toward the developing unit. The toner conveying path connects the toner inlet with the toner outlet. The shutter opens/closes the toner inlet and the toner outlet in linkage with an operation of attaching/detaching the toner case. The shutter integrally includes an inlet sealing member capable of opening/closing the toner inlet, and an outlet sealing member linked with the inlet sealing member and capable of opening/closing the toner outlet.
