Abstract: An image recording apparatus has a paper feeding system, a process unit for performing an electrophotographic process, a fixing system, an optical system, and a delivery system. The process unit is detachable from a main body through a front cover. The front cover has a container attached to its inner surface. The process unit can be divided into two parts which are separable from each other: a first part including a developer and a toner cartridge, and a second part including a photosensitive drum, a charger, a transferrer, and a cleaner. The paper feeding system is disposed on an upper portion of a main body of the image recording apparatus. The process unit and the fixing system are positioned diagonally below and forward of the paper feeding system such that a paper path connecting the paper feeding system and the fixing system descends forward. The optical system is disposed in a lower portion of the main body in such a manner as to partially underlie the process unit.
