Title: Cleaning device and image forming apparatus equipped therewith
Inventor: ISHINO MASATO
IPC: G03G21/10
Filed: 2007-03-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a cleaning device where a proper amount of toner is made to adhere to the surface of a cleaning roller and which holds suitable cleaning performance for the surface of an image carrier.  <P>SOLUTION: The cleaning device 60 is equipped with the cleaning roller 62 for removing an adhesive matter on the surface of a photoreceptor drum 21, and a scraper 65 that is a toner regulating member for regulating the amount of toner adhering to the surface of the cleaning roller 62. A part of the scraper 65, which comes into contact with the cleaning roller 62, is composed of material having a smaller Young's modulus than that composing a part of the scraper 65, which does not come into contact with the cleaning roller 62. Therefore, both the scraper 65 and the cleaning roller 62 are brought into contact with each other strongly by proper force at the contact part of the scraper 65 with the cleaning roller 62, and they are uniformly brought into contact with each other in all the area in the axial direction of the cleaning roller 62. Therefore, the uniform toner layer having proper thickness and free from irregularity is formed on the surface of the cleaning roller 62.  <P>COPYRIGHT: (C)2009,JPO&INPIT
