Abstract

A process cartridge (8) for an image forming apparatus, which includes a cartridge main body (24) having at least one of a developing device (25) for developing with toner a latent image on a photoconductor (14) and a cleaner (26) for salvaging the toner remaining on a surface of the photoconductor and detachably mounted to a main body of the image forming apparatus, and a shutter (49) which covers a covering area including an area beneath a lower part of the circumferential surface of the photoconductor (14) and an area beneath a lower part of at least one of a boundary between the photoconductor (14) and the developing device (25) and a boundary between the photoconductor (14) and the cleaner (26). The shutter (49) moves in a substantially horizontal posture between the covering area and a siding area beneath the developing device or the cleaner. Therefore, toner received by the shutter is prevented from falling from the shutter when the shutter is moved.
