PROBLEM TO BE SOLVED: To clean residual tonner in a development apparatus with a simple constitution.SOLUTION: A tonner cleaning tool 50 to be used for a cleaning device which cleans residual toner by making air flow into a development device 5 includes: a body part 52 having an internal space 52a into which an opening 33 side of a development roller 35 side of the development device 5 is inserted; a suction part 53 communicated with the internal space 52a, and connected to an external air suction device; and a protrusion part 54a for generating a clearance between an entrance seal 38 and the development roller 35 by pushing an entrance seal 38 for sealing a gap between the entrance seal 38 and the development roller 35 at the opening 33 when the development device 5 is inserted into the air cleaning position of the internal space 52a. When air is sucked by the air suction device, the tonner in the development device 5 is sucked with air, and discharged from the suction part 53 side. In this case, the air is made to flow from an opening 39 of the development device 5 after the start of suction. |
