Abstract

PURPOSE:To provide a device of simple constitution by providing a recovery part disposed in a photosensitive drum and the toner recovery circuit communicating with this. CONSTITUTION:A barrel-form toner recovery part 15 is so provided as not to rotate, in the central part of a photosensitive drum 1. It has openings 16, 17 at its top and bottom and the lower opening 17 is held shut by an openable cover 18. An opening 21 is formed in the nonimage region of the drum 1 so that the toners from the storage part 13 of a cleaning device 7 are received. An opening 23 is formed to the casing 22 of a developing device 4 and communicated with the opening 21 of the drum 1. An openable cover 24 is provided to the opening 23 in such a manner as to be opened and closed synchronously with the cover 15. When the toners deposit to a certain extent in the toner recovery part 15, the drum 1 is rotated 180 deg. to open the openings 17, 23 and return the toners into the developing device 4.
