Cleaning device and image forming apparatus

A cleaning device includes a cleaning member that removes toner from a surface of an image holder by bringing an upper end portion into contact with the surface from a downstream side in a rotation direction of the image holder, a housing that supports the cleaning member and that stores the toner removed from the surface of the image holder by the cleaning member, and a transport member that is provided in the housing and that transports the toner stored in the housing to an outside of the housing at the same height as a contact portion of the cleaning member that comes into contact with the surface of the image holder or at a position above the contact portion.

An image forming apparatus includes: an image carrier that carries an image; a developing device that develops a latent image formed on the image carrier into a visible image formed of powder; an intermediate transfer body to which the visible image is transferred from the image carrier and that temporarily transports the visible image; a transfer device that transfers the visible image on the image carrier to the intermediate transfer body; a first cleaning device that cleans the image carrier by collecting powder that remains on the image carrier; a first collection container that receives the powder collected by the first cleaning device; a second cleaning device that cleans the intermediate transfer body by collecting powder that remains on the intermediate transfer body; a second collection container that receives the powder collected by the second cleaning device; a feeding device that supplies a transfer-process bias to the transfer device; and a changing unit that changes the transfer-process bias supplied by the feeding device when a waste powder image is formed on the image carrier, the transfer-process bias being changed so as to adjust amounts of powder in the waste powder image received by the first collection container and the second collection container.

A sheet-member guide structure includes a first guide member that guides a sheet member from a fixing unit to a transport roller unit, the fixing unit fixing an image formed on the sheet member to the sheet member by heating the sheet member that is transported, the transport roller unit transporting the sheet member; and a second guide member that comes into contact with the sheet member to which the image has been fixed by the fixing unit and guides the sheet member to the transport roller unit, the second guide member being disposed downstream of the first guide member in a transporting direction in which the sheet member is transported and being made of a material having a thermal conductivity higher than a thermal conductivity of a material of the first guide member.

Sheet-member guide structure and image forming apparatus

An image forming apparatus includes a transfer unit configured to transfer second charged images superposed with one another onto a holding surface of a recording medium on which at least one first charged image has been electrostatically held and a static eliminating unit disposed upstream from the transfer unit in a transport direction of the recording medium and configured to remove static electricity from the recording medium electrostatically holding the at least one first charged image.

An image forming apparatus includes a transport belt, a first intermediate transfer belt, and a second intermediate transfer belt. The transport belt is disposed along a transport path extending in a vertical direction. The transport belt is configured to transport a recording medium while coming into contact with one surface of the recording medium. The first intermediate transfer belt is configured to sandwich the recording medium together with the transport belt. An image is transferred from the first intermediate transfer belt to the recording medium. The second intermediate transfer belt is disposed above the first intermediate transfer belt. The second intermediate transfer belt is configured to sandwich, together with the transport belt, the recording medium which is in a state where the recording medium is sandwiched between the first intermediate transfer belt and the transport belt. An image being transferred from the second intermediate transfer belt to the recording medium.

An image forming apparatus includes: a medium transport path; a first image transport path that is disposed so as to oppose the medium transport path and along which an image to be formed on the medium is transported; an image forming part that forms the image and is disposed adjacent to the first image transport path; and a second image transport path that is disposed so as to oppose the medium transport path, that is located at a distance from the image forming part, and along which an image to be formed on the medium is transported, the second image transport path, the first image transport path, and the medium transport path, together surrounding the image forming part.
