Abstract: A cleaning device includes a removal member that forms piled bodies of residual objects at a contact location and removes residual objects from a surface of a target cleaning member by contacting with the surface in a linear manner and rubbing against the surface, and a smoothing member that smooths out the piled bodies by moving along the contact location.

Abstract: An image forming apparatus, includes a forming device that forms unfixed images on recording media, a fixing unit that melts a material forming the images to fix the images onto the recording media, a stacking tray on which the recording media onto which the images are fixed are stacked, and a displacer that applies a force to the recording media stacked on the stacking tray to displace the recording media relative to each other.

Abstract: A cleaning device includes a removal member that removes residual objects from a surface of a target cleaning body by contacting with the surface in a linear manner and rubbing against the surface and forms a piled body which is constructed of a portion of the residual objects at a contact location, and a pressure device that presses the piled body to increase a strength of the piled body.

Abstract: A cleaning device that cleans a residual toner from a cleaning target includes a cleaning blade that blocks the residual toner containing toner particles and an external additive on the cleaning target and scrapes the residual toner from the cleaning target, a measurement unit that measures an amount of the external additive in the residual toner which is blocked by the cleaning blade and remains on the cleaning target, and a control unit that increases an amount of a toner that is supplied to the cleaning target based on a measurement result obtained by the measurement unit.

Abstract: Provided is a developing device including an accommodating unit that contains a developer, a transport member that holds the developer on an outer surface and transports the developer outside from the accommodating unit, a layer regulating member that faces the outer surface of the transport member with a gap, extends in a direction intersecting a direction in which the developer is transported, and regulates a layer thickness of the developer, and a removal member that is inserted into the gap, moves along the direction in which the layer regulating member extends, and removes the developer from the gap.

Abstract: Provided is a cleaning unit including a removing member that contacts with a surface of a cleaning target and removes adherent matters on the surface of the cleaning target, a storage section that stores the adherent matters removed by the removing member, and a supply member that has a blade and rotates the blade in the storage section to supply some of the adherent matters stored in the storage section to the surface of the cleaning target.

Abstract: Provided is a toner transport device including a transport member that transports a developer in one direction, a toner feeding member disposed adjacent to, in a direction crossing the one direction, an end portion of the transport member, and a housing that is provided with a toner receiving port which receives supply of toner in an upper section of the toner feeding member, and accommodates the transport member and the toner feeding member, wherein the toner feeding member includes a rotating shaft, and a flat plate portion that protrudes in a direction away from a shaft member with one side thereof being connected to the shaft member and a front end portion away from the shaft member having a tapered shape, the flat plate portion rotating along with rotation of the shaft member to scrape the toner that moves from the toner receiving port toward the toner feeding member.

Abstract: A developing device includes: a container that contains a developer including toner; a partition that forms a plurality of chambers by partitioning an interior space of the container; an agitation mechanism that agitates the developer in the interior space and moves the developer between the plurality of chambers; a transport section that is supplied with the developer from the container, and transports the developer to a surface of an image carrier that carries an electrostatic latent image such that the transported developer is close to or contacts the surface of the image carrier, thereby developing the electrostatic latent image; and a driving mechanism that moves at least the partition.
