Abstract
An image forming apparatus includes an image forming portion, a fixing portion, a housing configured to accommodate the image forming portion and the fixing portion and having an opening portion through which an outside of the housing and an inside of the housing communicate with each other. A photosensitive member includes a conductive base body and a surface layer portion formed on an outer periphery of the base body. In a case where a thickness of the surface layer portion is a distance from an outer peripheral surface of the base body to a surface of the photosensitive member, a maximum particle diameter of particles capable of passing through the filter is smaller than the thickness of the surface layer portion.
