A sheet tray includes a first tray and a second tray each including a first friction portion or a first contact portion, and a second friction portion or a second contact portion. In a process of movement of the second tray from a first position to a second position, the first friction portion contacts the first contact portion to deform the first contact portion and starts returning the first contact portion from a deformed shape to an original shape when the second tray is located at a position spaced apart from the second position in a second direction. The second friction portion contacts the second contact portion when the second tray moved from the first position in a first direction has reached the second position, and the second friction portion deforms the second contact portion when the second tray is moved from the second position in the first direction.

There is provide a conveying apparatus conveying a sheet including: a main body formed with a conveyance path; a first feed tray installable in the main body at a first position; a discharge tray; and a first regulating section performing regulation for regulating movement of the first tray, in a state of being located at a second position, toward the other side in a first direction. The first regulating section is configured to release the regulation, in a case that the first feed tray, at the second position, is moved upwardly by a first predetermined moving amount. A spacing distance in the up/down direction between the first feed tray and the discharge tray is shorter than the first predetermined moving amount. The discharge tray is configured to be move upwardly by being contacted with the first feed tray in a case that the first feed tray is moved upwardly.

A sheet feeding apparatus is provided with a pick-up roller that contacts sheets loaded on a load tray to pick up, a paper feed roller that feeds a picked-up sheet, and a separation roller brought into press-contact with the paper feed roller to separate the sheet, where the sheets are separated from the pick-up roller, the separation roller is rotated in a sheet return direction different from a sheet feed direction, and subsequently, the paper feed roller is separated from the separation roller. It is possible to prevent damage to a sheet and sheet jam from occurring in pulling out the load tray loaded with sheets to the front side.

An image forming apparatus includes: a drum cartridge to which one of a first toner cartridge and a second toner cartridge is attachable; a frame including a first slot and a second slot; and a controller including a control memory and a processor. The drum cartridge to which the one of the first toner cartridge and the second toner cartridges is attached is attachable to one of the first slot and the second slot. The control memory stores first color information allocated to the first slot, and second color information allocated to the second slot. In a state where the drum cartridge is attached to one of the first slot and the second slot and when the drum memory does not store any color information, the processor is configured to perform: writing, into the drum memory, one of the first color information and the second color information which is appropriate.

The present sheet processing apparatus is to obtain that folding in the center portion in the width direction of sheets is made, folding in the end portion is made more reliably by repeatedly pressing the end portion in the width direction, the folded sheets are harder to open, the appearance is also enhanced, and that collection characteristics are improved in stacking bunches of folded sheets, a sheet processing apparatus is provided with pairs of press members (press rollers 70) that press a folded loop BL of folding sheets BS, and a support unit 56 that shifts in the width direction of the folding sheets, while supporting a plurality of rows with a distance between the press members narrowed stepwise in the shift direction.

Provided are an accommodating device that performs appropriate processing in order to discard an empty paper pack remaining in the accommodating device and an image forming apparatus including the accommodating device. The accommodating device includes an accommodating unit, a processing unit, and a discarding unit. The accommodating unit accommodates a paper pack including a bundle of stacked sheets of printer paper wrapped with wrapping paper in such a manner that the printer paper is freely taken out. The processing unit flatly crushes and conveys an empty paper pack from which all of the sheets of the printer paper have been taken out and in which only the wrapping paper has remained. The discarding unit stores a flatly crashed empty paper pack conveyed from the processing unit in order to discard them.

According to one embodiment, an image forming apparatus includes a printer and a controller. The printer performs image formation on a sheet at a first speed relating to a speed of image formation or at a second speed slower than the first speed. The controller acquires information on deterioration of developer contained in an own apparatus, and controls the printer to perform image formation at the first speed when the information does not satisfy a predetermined condition indicating that the developer is deteriorated and to perform image formation at the second speed when the information satisfies the predetermined condition.

An image forming apparatus includes a printer unit including a sheet ejection tray located on an upper surface of the printer unit; a scanner unit spaced above the sheet ejection tray of the printer unit in a vertical direction; an operation unit disposed at a front end portion of the scanner unit, the operation unit including a touchscreen; a cover covering a bottom side of the touchscreen in the vertical direction; and a fixing portion fixing the cover to the front end portion of the scanner unit. The cover includes a support portion that, when projected on an imaginary horizontal surface, overlaps a part of the touchscreen. The support portion is shaped like a box extending in the vertical direction and is coupled to a portion of the upper surface of the printer unit adjacent to the sheet ejection tray.

An electrophotographic image support includes: a conductive support; a photosensitive layer disposed on the conductive support; and a protective layer disposed on the photosensitive layer, the protective layer being formed of a polymerized cured product of a radically polymerizable composition containing a radically polymerizable monomer and a perfluoropolyether compound having a radically polymerizable functional group, the perfluoropolyether compound having the radically polymerizable functional group being represented by the following formula (1):

[Chemical Formula 1]

(B).sub.l-A-CF.sub.2O(CF.sub.2CF.sub.2O).sub.m(CF.sub.2O).sub.nCF.sub.2-A-(B).sub.l  (1)

wherein A represents a linking group having a molecular weight of 100 or more and 400 or less, B represents a radically polymerizable functional group, l represents an integer of 2 or more, and m and n each represent an integer of 0 or more, wherein m+n≧1.

An image forming apparatus, having a photosensitive drum, an intermediate transfer belt located at a lower position with respect to the photosensitive drum to contact the photosensitive drum, a secondary transfer roller contacting the intermediate transfer belt, a first sheet tray located at a lower position with respect to the intermediate transfer belt to store a sheet, and a sheet guide to guide the sheet stored in the first sheet tray to a position between the intermediate transfer belt and the secondary transfer roller, is provided. The sheet guide is located between the intermediate transfer belt and the first sheet tray with regard to a vertical direction and has a curved section. A contact area between the secondary transfer roller and the intermediate transfer belt is located at a lower position with respect to an upper end portion of the curved section.
