Developing Device, Waste Toner Collecting Device and Image Formng Apparatus having the Same

摘要

An image forming apparatus includes a photosensitive medium (31) on which an electrostatic latent image is formed, an exposure unit to irradiate light onto the photosensitive medium (31), a developing device (51) to apply toner to the photosensitive medium (31) having the electrostatic latent image formed thereon, a cleaning device (42) to remove waste toner remaining in the photosensitive medium (31), and a waste toner collecting device (60) to store the waste toner removed from the photosensitive medium (31). The waste toner collecting device (60) is provided with a supporting rail (61) to support the developing device (51). The waste toner collecting device (60) includes the supporting rail (61) that supports the developing device (51), so that additional components to support the developing device (51) are not needed, and the whole size of the image forming apparatus is reduced.
