摘要： 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(θ)=μ2−μ1×(Ntp/Nbt+cosθ)>0. Here μ1 is the friction coefficient between toner and image carrier, μ2 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 θ is the angle formed by the blade and image carrier (the cleaning angle).

摘要： An image forming apparatus of the present invention includes a cleaning brush positioned upstream of a blade nip in the direction of movement of the surface of a photoconductive drum. To prevent toner from accumulating at the blade nip, the surface of the photoconductive drum is moved in the direction opposite to the regular direction for image formation, conveying toner accumulated in a wedge-shaped space upstream of the blade nip 2n to a position where the cleaning brush removes it. With this configuration, the image forming apparatus can stably clear spherical toner particles left on the drum over a long period of time.

摘要： A cleaning device cleans off a toner from a surface of a member rotating in a first direction. The cleaning device includes a blade made of an elastic material including a tip portion with a slanting portion that is pressed against the surface in a second direction counter to the first direction. A supporter supports the blade. An angle between the slanting portion and a longitudinal direction of the blade is obtuse. The slanting portion is pressed against the surface at a surface pressure of 2.0 MPa or more.
