Abstract
An image forming device including toner image forming means that forms toner images on the surface of an image carrier, transfer means that transfers the toner images on the surface of the image carrier onto a transfer member, and a plate shaped cleaning blade. The cleaning blade is configured to contact the surface of the image carrier at a pressure of greater than 40 N/m and to scrape off residual toner remaining on the surface of the image carrier after the transfer process by the transfer means has been completed. The surface of the image carrier has a static coefficient of friction with a sheet as measured by the Euler belt type coefficient of friction measurement method of 0.5 or greater, and the cleaning blade has a static coefficient of friction with a polytetrafluoroethylene tape in the range 1.0 to 2.0.
