摘要:
A cleaning unit includes a first blade and a second blade. The first blade is in contact with an image carrier or a paper carrier and removes adhered substances remained on surface of these. The second blade has an abrasive layer that is formed by including abrasive particles in an elastic material and is disposed in the downstream side of the first blade. The second blade is allowed to be in contact with the image carrier 1 or the paper carrier. Volume occupancy of abrasive particles in an area of contact of the second blade with either the image carrier or the paper carrier is not less than 50 percent and not more than 90 percent.

An image forming apparatus includes an image bearing member configured to form an electrostatic latent image on a surface thereof, and a separating mechanism configured to separate an irregular charge toner from a residual toner remaining on the surface of the image bearing member after a completion of an image forming process, to provide an extra travel passage to give a time delay to the irregular charge toner, and to return the irregular charge toner with the time delay to the surface of the image bearing member.
摘要:
An image forming apparatus including a latent image bearing member, a charger, a latent image forming device, a developing device, a surface moving member, a transfer device, a cleaner having a cleaning blade and an irradiating device configured to discharge the latent image bearing member. This developing device is configured to develop images with a toner having a circularity not less than 0.94. The irradiating device is disposed on the upstream from the cleaner relative to the rotation direction of the latent image bearing member.

An imaging apparatus that is capable of realizing good cleaning characteristics and transfer characteristics, and obtaining a high quality image using toner having a high average roundness is provided. The imaging apparatus includes an image carrier, a charge unit, a developing unit, a transfer unit, and a cleaning unit. The transfer unit may directly transfer a toner image onto a recording medium that is carried by a transfer belt, or transfer the toner image onto the transfer belt first to then transfer the toner image onto the recording medium from the transfer belt. The cleaning unit includes a cleaning blade and a brush roller. The toner used in the imaging apparatus has an average roundness Ψ within a range of 0.93˜0.99, and a friction coefficient μs of the image carrier satisfies a condition, friction coefficient μs≦3.6−3.3×average roundness Ψ.

A cleaning device, a process cartridge, an image forming apparatus and toner are disclosed to maintain improved cleaning performance for a long time. The cleaning device includes a cleaning blade, an antifriction agent coating part and a toner removing part. The cleaning blade is disposed in contact with a surface of an image support body. The antifriction agent coating part coats a solid antifriction agent on the surface of the image support body, and is disposed in an upstream side from the cleaning blade with respect to a rotational direction of the image support body. The toner removing part removes toner particles, and is disposed in an upstream side from the antifriction agent coating part with respect to the rotational direction of the image support body.
