Abstract: In a process head for electrophotographic apparatus integrally formed with a charing/exposing chamber, a developing chamber, a drying chamber and a fixing chamber along the feeding direction of the film for recording and thereby made capable of processing plural frames of the recording film simultaneously, stage heads which constitute the respective processing chambers are fixed to a mounting member and a portion with charging mechanism is detachably inserted in the interval space between the stage head corresponding to the charging/exposing chamber and the mounting member so that its maintenance can be facilitated and the apparatus as a whole can be made compact in size.
