A device incorporated in an electrophotographic image recorder for collecting toner particles, paper dust and so on which are removed from a photoconductive element by a cleaning device. The collecting device 50 is constructed independently of the cleaning device 32. In a portion where the collecting device and cleaning device are connected to each other, a first and a second shutter 60, 86 which open and close respectively an opening formed through the cleaning device 62 and an opening 84 formed through the collecting device cooperate with each other. When the collecting device 50 is connected to the cleaning device 32, the second shutter 86 unblocks the associated opening 84 before the first shutter 60 does so. Conversely, when the collecting device 50 is disconnected from the cleaning device 32, the second shutter 86 blocks the associated opening 84 after the first shutter 60 has done so. <IMAGE>
