Title:
クリーニング装置、プロセスカートリッジ、画像形成装置
Document Type and Number:
Japanese Patent JP4509519
Kind Code:
B2
Abstract:
A cleaning device and process cartridge including the same for an image formation apparatus, which prevents cleaning failures due to toner slipping past a blade, based on an equation for the force of toner particle rotation and the restraining force. Toner on an image carrier is removed by a blade. The relation between the blade and the image carrier satisfies the equation f(theta)=mu2-mu1x(Ntp/Nbt+costheta)>0. Here mu1 is the friction coefficient between toner and image carrier, mu2 is the friction coefficient between toner and blade, Ntp is the adhesive force between toner and image carrier, Nbt is the force received by the toner from the blade, and theta is the angle formed by the blade and image carrier (the cleaning angle).
