An image forming apparatus forming an image on a recording medium, includes: a developing device that forms a toner image on an image carrier, a transfer device that transfers the toner image formed by the developing device to a recording medium at a transfer position, and a charge eliminator that is arranged upstream of the transfer position in a conveyance direction of the recording medium and eliminates charges of the recording medium in a non-contact manner, wherein the charge eliminator is an ionizer and is arranged at a position which is away by a predetermined distance from a conductor for moving ionic particles generated at the time of charge elimination.

Image forming apparatus

An image forming system includes: an image forming apparatus that includes a transfer device that transfers a toner image onto a sheet and a fixing device that fixes the toner image; a sheet heating device that heats the sheet on an upstream of the fixing device in a sheet conveyance direction; a first detector that detects a temperature inside the image forming apparatus; a second detector that detects a temperature of the sheet before the sheet heating device heats the sheet; and a controller that causes the sheet heating device to heat the sheet based on a detection result by the second detector and a sheet passing condition of the sheet, and corrects at least one of a transfer current and a transfer voltage in the transfer device based on a detection result by the first detector in a case where the sheet heating device heats the sheet.

Image forming system, image forming apparatus, and recording medium

An image forming apparatus which forms a toner image on an image carrier based on image formation data, and transfers the toner image onto a sheet having an unevenness on a surface and forms an image, the image forming apparatus including a hardware processor which detects a parameter value regarding a charging amount of a toner that forms the toner image, sets a size of a dot of the toner image according to the detected parameter value, and generates the image formation data of the dot of the set size.

Image forming apparatus and computer readable storage medium storing program

An image forming apparatus which transfers, onto paper, a toner image formed on a belt-shaped image carrier including an elastic layer on a surface thereof, and forms an image includes a rigid blade which cleans the surface of the image carrier in contact with the image carrier which has transferred the toner image onto the paper; a roller which is upstream of the rigid blade in a rotation direction of the image carrier, and cleans the surface of the image carrier upstream of the rigid blade by coming in contact with the image carrier which has transferred the toner image onto the paper; a rigid blade holder which holds the rigid blade; and a roller holder which holds the roller. The rigid blade holder and the roller holder are installed with a gap therebetween.

Image forming apparatus with separately housed cleaning blade and cleaning roller

A cleaning apparatus cleans an image carrier including an elastic layer after a toner image formed on the image carrier is transferred to a transfer material. The cleaning apparatus includes a rigid blade that cleans a residue attached on a surface of the image carrier by contacting the image carrier from which the toner image has been transferred to the transfer material. The rigid blade includes a metal base and a coating layer formed on a surface of the metal base. The coating layer is disposed at least at an edge portion of the base that contacts the image carrier. An upstream part of the edge portion has a rounded shape with a radius of curvature that is less than an average radius of toner particles.

Cleaning apparatus, image forming apparatus and method for producing rigid blade

A cleaning apparatus which cleans an image carrier that has an elastic layer after a toner image formed on the image carrier is transferred onto a transfer object, the cleaning apparatus including: a cleaning blade which contacts the image carrier and removes a residue attached to the image carrier; a change section which changes a cleaning condition of cleaning by the cleaning blade; and a hardware processor which controls the change section to change the cleaning condition in accordance with deterioration of the image carrier.

Cleaning apparatus, image forming apparatus and cleaning method

An image forming apparatus which transfers a toner image formed on an image carrier onto a transfer object and forms an image, the apparatus including: a cleaner which has a rigid blade made of metal that contacts the image carrier after transferring of the toner image onto the transfer object and cleans a residue attached to a surface of the image carrier, wherein the image carrier has a base layer and an elastic layer, and a surface hardness of the elastic layer measured by a nanoindentation method is 70 MPa or more and 150 MPa or less, and a thickness of the rigid blade is 100 &#x3bc;m or more and 300 &#x3bc;m or less.

Image forming apparatus and cleaning apparatus having a rigid metal blade cleaner

An image forming device includes: an image carrier on which a toner image is formed; and a cleaning blade which removes a residual material on the image carrier after the toner image is transferred to a transferred body, wherein the image carrier includes an elastic layer, the cleaning blade is a metallic plate spring, and a tip end of the cleaning blade is pressed against the image carrier by restoring force of the plate spring.

Image forming device

An image forming apparatus transfers a toner image formed on an image carrier having a moving surface onto a transfer object, and includes: a cleaning member that performs a removal operation on residues remaining on the image carrier after transfer of the toner image; and a brush member that has bristles including original yarns with uneven surfaces formed by microparticles adhering to and coating the original yarns, and comes into contact with the image carrier, on a downstream side relative to the cleaning member in a movement direction of the surface of the image carrier, to remove part of the residues that remains unremoved on the image carrier even after the removal operation performed by the cleaning member.
