PROBLEM TO BE SOLVED: To provide a drum unit allowing a cleaning device to achieve an always high toner dispersion preventing function without being influenced by an environment and capable of enhancing destaticizing performance on a surface of a photoconductor drum by preventing attenuation of light from a destaticizer.SOLUTION: In a drum unit 1M allowed to be attached/detached to/from a printer body (image forming apparatus body) 100 and including at least a photoconductor drum 3a and a cleaning device 5a, a part of the toner penetration side of a resin housing 28 of the cleaning device 5a is constituted of a metal member 33 and a toner dispersion preventing seal 34 is stuck to the metal member 33. Further, a destaticizer 25 is arranged on the upstream side of the cleaning device 5a in a rotation direction of the photoconductor drum 3a and the metal member 33 is arranged so that the main plane of the metal member 33 faces a destaticizing optical path of the destaticizer 25. |
