A printing apparatus has a first binding unit for performing a binding process at any one of plural positions and a second binding unit for performing a binding process at a single position and prints images based on image data on sheets. If the binding process is performed using the first binding unit, the printing apparatus prints images on sheets according to the input order of the image data. If the binding process is performed using the second binding unit, the printing apparatus prints images on sheets according to the input order of the image data, or prints the images according to an order reversed from the input order of the image data, based on the orientation of the images of the image data, the single position and the orientation of the sheets used for printing.

A post-processing apparatus includes a storing unit in which plural recording media are stored for performing post-processing and a transport member that transports a recording medium to the storing unit as a result of rotating while being in contact with a surface of the recording medium. The transport member includes a blade that comes into contact with a recording medium and a reinforcing portion that reinforces a strength of a portion of the blade that does not come into contact with the recording medium.

A toner image is formed on a sheet based on image data by an image forming portion, and a plurality of sheets on which the toner image is formed is bound together by a stapleless binding unit including a pair of tooth-like members, each having a concave and convex portion. Then, the image data is corrected by a correction portion so that a ratio of toner within a part of the sheet to be subjected to binding processing by the stapleless binding unit is equal to or smaller than a predetermined value.

A medium processing apparatus includes a liquid applier, a post-processing device, a liquid storage unit, a mover, and a liquid supplier. The liquid applier applies liquid to at least one medium. The post-processing device performs a given process on a bundle of media including the at least one medium on which the liquid is applied by the liquid applier. The liquid storage unit stores the liquid to be supplied to the liquid applier. The mover causes the liquid applier to move in a reciprocating direction orthogonal to the conveyance direction. The liquid supplier supplies the liquid from the liquid storage unit to the liquid applier and includes an extensible member having an elastic cylindrical part on at least a part of the liquid supplier. The extensible member extends in the reciprocating direction of the mover.

A post-processing device includes: a loading section that has a loading surface directed obliquely upward and in which a recording medium is loaded on the loading surface in a state where one end of the recording medium is directed downward; a supporting section that supports the one end of the recording medium loaded on the loading surface; a transporting section that is provided at a position facing an upper portion of the loading surface and that transports the recording medium downward toward the loading surface; and a pushing section that pushes a non-facing surface of the recording medium, which is opposite to a facing surface facing toward the loading surface, toward the loading surface to move the recording medium toward the loading surface, in a contact state where a part of the recording medium transported by the transporting section on a side of the one end comes into contact with the loading surface and a part of the recording medium on a side of an upper end is separated from the loading surface and comes into contact with the transporting section.

A post-processing device includes: a loading section on which a bundle of recording media subjected to folding processing is loaded; a pushing section that moves in a thickness direction of the bundle of recording media, comes into contact with a surface, and pushes the bundle of recording media to form a folded portion; and a rotating section that starts an operation from a stopped state after the pushing section moves to a predetermined position, and sandwiches and rotates the folded portion of the bundle of recording media pushed by the pushing section to form a fold in the bundle of recording media.

A post-processing device includes: a loading section that has a loading surface directed obliquely upward and in which a recording medium is loaded on the loading surface in a state where one end of the recording medium is directed downward; a supporting section that supports the one end of the recording medium loaded on the loading surface; and a correcting section that has a facing surface facing toward the loading surface and that corrects deflection of the recording medium by coming into contact with the recording medium in a posture in which a lower end portion of the facing surface approaches closer to the loading surface than an upper end portion from a side of the recording medium, which is loaded on the loading surface, opposite to the loading surface and by thereafter coming into contact with the recording medium while moving such that the upper end portion approaches the loading surface in a state where the lower end portion is in contact with the recording medium.

A post-processing device includes: a loading section that has a loading surface directed obliquely upward and in which a recording medium is loaded on the loading surface in a state where one end of the recording medium is directed downward; a supporting section that supports the one end of the recording medium loaded on the loading surface; a transporting mechanism that transports a plurality of recording media transported one by one toward the loading section by shifting and stacking the recording media in a transport direction, and sets an amount of shift of the recording media on the basis of a predetermined condition; and a transporting section that bends each of the plurality of recording media transported from the transporting mechanism by applying a transport force to an upper end of each of the recording media opposite to the one end in a state where the one end is in contact with the supporting section, and separates one by one the recording media and loads the recording media on the loading surface.

A post-processing device includes: a loading section that has a loading surface directed obliquely upward and in which a recording medium is loaded on the loading surface in a state where one end of the recording medium is directed downward; a supporting section that supports the one end of the recording medium loaded on the loading surface; a restricting section that restricts bending of the recording medium by coming into contact with the recording medium loaded on the loading surface; and an abutting section that abuts the one end of the recording medium against the supporting section by pushing an upper end of the recording medium opposite to the one end downward, in a state where the restricting section restricts the bending of the recording medium.

A post-processing apparatus includes a storing unit in which plural recording media are stored for performing post-processing and a transport member that transports a recording medium to the storing unit as a result of rotating while being in contact with a surface of the recording medium. The transport member includes a blade that comes into contact with a recording medium and a reinforcing portion that reinforces a strength of a portion of the blade that does not come into contact with the recording medium.
