An image forming apparatus includes an electrophotographic photoreceptor, a charging device, an electrostatic latent image forming device, a developing device, a transfer device, and a cleaning device, and further includes an intercepting device that includes an intercepting member separated from the electrophotographic photoreceptor by a gap so that a distance from the surface of the electrophotographic photoreceptor to the intercepting member is about 0.3 to 0.9 (inclusive) times a volume-average particle size of toner particles. The intercepting member is used to intercept residual toner particles at a position downstream of the transfer device and upstream of the cleaning device in a rotation direction of the electrophotographic photoreceptor, the residual toner particles remaining on the surface of the electrophotographic photoreceptor.

An image forming apparatus includes a rotatable image bearing drum; a toner image transfer device; a cleaning blade for cleaning the drum after transfer of the image; a rotatable furbrush provided downstream of the transfer device and upstream of the blade, the furbrush being rotatable counterdirectionally with respect to a peripheral movement of the drum; an executing portion for executing a first mode for forming an image on the transfer material on the basis of a signal inputted to the apparatus and a second mode for supplying a band of the toner to the blade; and a controller for controlling a peripheral speed difference between the drum and the furbrush, wherein the difference when the band of the toner passes the furbrush in the second mode is smaller than that when the toner on the drum after the image transfer passes the furbrush in the first mode.

An image forming apparatus includes an image forming portion configured to form a toner image on a recording material with a liquid developer containing a toner and a carrier liquid, wherein the carrier liquid contains a first substance for imparting an electrical polarity to the toner and a second substance, higher in volume resistivity than the first substance, as a dispersion medium for dispersing the toner; and a carrier separating device configured to separate the carrier liquid into the first substance charged to an opposite polarity to a charge polarity of the toner and the second substance by applying an electric field to the liquid developer collected from the image forming portion so as to collect each of the first substance and the second substance.

A cleaning body includes a shaft and an elastic layer that is helically wound around the shaft from one end side to the other end side of the shaft and fixed on the shaft and that cleans a body to be cleaned while the elastic layer rotates. The elastic layer includes a division portion having plural divided segments and having a length of from 20% to 70% of the full length of the elastic layer. The division portion is located in a longitudinal central portion of the elastic layer. In the sectional view perpendicular to the axial direction of the shaft, a minimum thickness part in the longitudinal central portion of the elastic layer is from 5% to 12% thicker than a minimum thickness part in each longitudinal end portion of the elastic layer.

An image formation apparatus includes: an image carrier; a developing device which develops an electrostatic latent image formed on the image carrier as a toner image; a transfer device which transfers the toner image to a medium; a cleaning device which recovers toner remaining on the image carrier after the toner image is transferred; and a lubricant application adjustment mechanism which applies a lubricant on the image carrier and recovers toner present on the image carrier upstream of the cleaning device; and a controller which controls the lubricant application adjustment mechanism. The controller causes the lubricant application adjustment mechanism to recover more toner when the toner image formed on the image carrier has a larger image area ratio.

A cleaning device, which is included in a process cartridge and an image forming apparatus, includes a cleaning blade configured to remove a material attached to a surface of an image bearer, a cleaning case configured to contain the material removed by the cleaning blade, and a removed material receiver configured to receive the material failed to enter into the cleaning case when the material is removed by the cleaning blade, the removed material receiver having a first range at both ends in a width direction of the cleaning blade and a second range at a center in the width direction of the cleaning blade. A volume per unit length in a width direction of the first range is greater than a volume per unit length in a width direction of the second range.

A toner collecting device includes an exhaust path and a catching installation. Through the exhaust path, air containing a floating toner is passed. The catching installation is configured to catch the floating toner from the air passing through the exhaust path. The catching installation is formed by overlapping a plural of filters each having a different mesh size.

Cleaning a photoconductive surface (16) from particles and excess fluid with at least two wiper blades, wherein a first wiper blade (12) is to contact the photoconductive surface (16) and to wipe at least some of the particles and at least some of the excess fluid from the photoconductive surface (16) and wherein a second wiper blade (14) is to contact the photoconductive surface (16) and to wipe at least some of the particles and at least some of the excess fluid that have passed the first wiper blade, from the photoconductive surface (16).

In one example, a method for calibrating a position of a charge roller is described. The method may include a processor positioning a first end of a charge roller to a first plurality of index positions, determining a capacitance between the charge roller and a photoconductor imaging plate at each of the first plurality of index positions, determining a first index position of the first plurality of index positions with a greatest change in capacitance, and calibrating a position of the charge roller based upon the first index position.

A cleaning device includes multiple cleaners, a partition, and a holder. The multiple cleaners include a first cleaner and a second cleaner adjacent to the first cleaner. The multiple cleaners each include a cleaning roller to remove a substance adhering to a surface of an object and a housing having an opening to collect the substance. The partition partitions the first cleaner and the second cleaner and defines a part of a wall of each of the first cleaner and the second cleaner. The holder holds the multiple cleaners.
