An electrophotographic imaging device having a method of printing which includes setting a default toner density for printing; developing a first toned image having the default toner density; printing the first toned image on a first page of a print job; and before printing a second page of a print job, determining whether a duty cycle state of a photoconductive member in the imaging device has changed, and upon a positive determination, developing a second toned image having a toner density derived from the default toner density and printing the second toned image on the second page.

An apparatus converts image data based on a conversion condition, forms an image using a developer, measures the developer, and a humidity. The apparatus determines a first density of an image when a mode of the apparatus changes from a power saving mode in which the apparatus cannot form an image to a normal mode in which the apparatus can form an image, from values measured, based on a first determination condition, determines a second density of an image when the apparatus has formed images on a predetermined number of sheets in the normal mode, from values measured, based on a second determination condition that is different from the first determination condition, and generates the conversion condition based on the first density and the second density.

An image forming apparatus includes: an image formation part that forms an image on a paper sheet; a conveyor that includes a plurality of conveying members and conveys the paper sheet; a hardware processor that acquires information on a smudge on a paper sheet on which an image has been formed by the image formation part, and identifies, from the plurality of conveying members, one or more dirty conveying member(s) that may have caused the smudge based on at least one of the information on the smudge, information on the conveying members, and information on a job for image formation executed by the image formation part.

An image forming apparatus includes an image forming device, a gradation adjustment mark adder and a hardware processor. The hardware processor monitors and adjusts a gradation characteristic based on a result of scanning a gradation adjustment mark. The hardware processor makes a determination as to whether to form the gradation adjustment mark overlapping an image area of an image based on image data. If it is determined to form the gradation adjustment mark overlapping the image area, the hardware processor controls the gradation adjustment mark adder to add gradation adjustment mark information to the image data in the image area.

An image reading apparatus includes a reader, a conveying path, a conveyer, a conveyer housing, and a frame. The conveying path guides the sheet having the image to a reading position and guides the sheet read by the reader in an ejecting direction. The conveyer conveys the sheet along the conveying path. The conveyer housing supports the conveying path and the conveyer. The frame comprises columns and beams that connect adjacent columns. The frame individually fixes the reader and the conveyer housing. The columns are provided with resilient conveying-housing fixing members, the conveying-housing fixing members each having a length smaller than the distance between adjacent columns. The conveying-housing fixing members comprise a material having rigidity lower than the material of the beams. The conveyer housing is fixed to the frame by the conveying-housing fixing members. The reader is fixed to the beams.

An image forming apparatus includes an image forming section to form a correction pattern, a reading unit to read the pattern and generate first data, a color converter to convert the first data into second data, a memory to store density conversion data for a recording medium, a determiner to determine whether the memory contains the conversion data for the recording medium the pattern is formed, an acquisition unit to acquire spectral measured by an external colorimeter the memory does not contain the conversion data, a first density converter to convert the spectral data into density data, a density conversion data generator to correlate the second data and the density data and generate the conversion data, a second density converter to convert the second data into the density data using the conversion data, and a correction curve generator to generate correction curve data based on the density data.

An image forming apparatus includes an image bearing member, a voltage applying portion, a feeding portion, a detecting portion, a storing portion, a controller for controlling a first operation in which on the basis of a detection result of the detecting portion, a kind of the recording material set in the feeding portion is stored in the storing portion, and a second operation in which an adjusting chart is outputted for adjusting a transfer voltage; and an inputting portion. In response to a single start instruction, the controller is capable of carrying out control so as to execute the first operation and the second operation for outputting the adjusting chart prepared by transferring a plurality of test images onto the recording material from which an index interrelating with the kind of the recording material is detected by the detecting portion in the first operation.

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.
