Abstract

In an image forming apparatus, a developing device has a toner container having a toner outlet, and a receptacle having a mount portion for removably mounting the container. The insertion space of the mount portion and the toner outlet are each tapered such that the width in the up-and-down direction sequentially decreases toward the deepest end. In a developing device of the type causing the container to be rotated to bring the toner outlet into alignment with a toner inlet formed in the receptacle, the edge portion of the toner outlet is tapered to reduce a load during rotation and to ensure close contact at the end of the mounting of the container.
