ELECTROSTATIC IMAGE DEVELOPING TONER, CLEANING DEVICE, METHOD AND DEVICE FOR FORMING IMAGE

摘要

PROBLEM TO BE SOLVED: To provide a cleaning device capable of effectively removing toner left after transfer performed on an image carrier. SOLUTION: The cleaning device is used for an image forming method for forming an electrostatic image on the image carrier, developing the image with toner having a ratio of a volume averaged grain size to a number averaged grain size (volume averaged grain size/number averaged grain size) of 1.01 to 1.25, and also, having an average circularity of 0.950 to 0.995, and transferring the toner image to a transfer material directly or through an intermediate transfer body, and then, cleaning the toner left on the image carrier after the toner image is transferred. A voltage is applied on a cleaning means so as to form an electrical field on the image carrier between the image carrier and the cleaning means, and then, the toner left after transfer on the image carrier is attracted by the cleaning means.
