Abstract
An electrophotographic image forming apparatus includes a main frame, and a tray being movable between an inner side position located inside of the main frame and an outer side position located outside of the main frame while supporting process cartridges. The tray has, in its interior, hollow portions through which outside air passes, an inlet that introduces the outside air into the hollow portions, and outlets through which the outside air introduced into the hollow portions is discharged so as to impinge on the process cartridges.
