摘要： An image forming apparatus includes a photoconductive element including a conductive support rotatably supported and a charge injection layer and a surface protection layer sequentially laminated on the conductive support. A charger includes a conductive body for injecting, when a preselected voltage is applied thereto, a charge in the charge injection layer in contact with the surface protection layer. A writing unit exposes the charged surface of the photoconductive element imagewise to thereby locally vary the potential deposited on the photoconductive element and electrostatically form a latent image. A developing unit develops the latent image to thereby produce a corresponding toner image. The toner image is transferred from the photoconductive element to a recording medium. Assuming that the charge injection layer has a thickness of D micrometers, and that the potential deposited on the surface of the photoconductive element by the conductive member is V volts in absolute value, then a ratio V/D is confined in a preselected range that does not contaminate the background of the photoconductive element.

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).
