An information processing apparatus includes print condition receiving portion, save information holding portion, save information re-setting portion, print data generating portion. Save information holding portion temporarily holds a set value of a predetermined setting item among setting items of print conditions that have already been received via print condition receiving portion. Save information re-setting portion, after print condition receiving portion restarts the input of the print conditions, reads out the set value held by save information holding portion and set the set value in a corresponding setting item of the print conditions. Print data generating portion, after a print execution instruction is input via print condition receiving portion, generates print data in accordance with the print conditions received by print condition receiving portion. The print data generated by print data generating portion is printed by an image forming portion of a printing apparatus.

Information processing apparatus, printing apparatus, printing system, and computer-readable non-transitory storage medium

The preview unit displays on a display a preview image of image data in the image data retaining unit. The position receiving unit receives a position that user designates on the preview image displayed on the display. The selection receiving unit receives a user selection of additional information retained in the additional information retaining unit. The information imparting unit imparts the additional information received by the selection receiving unit to the position received by the position receiving unit. The image processing unit extracts a page imparted with the additional information from the image data in the image data retaining unit, and executes the processing associated with the additional information.

Image processing apparatus

The present invention provides an electrophotosensitive material comprising a conductive substrate and a photosensitive layer provided on the conductive substrate, wherein the photosensitive layer contains a polyarylate having a repeating unit represented by the general formula (1): wherein X represents a phenylene group, a naphthylene group, or a biphenylene group, as a binder resin. The polyarylate is contained in the amount of 30% by weight or more based on the entire binder resin. The electrophotosensitive material of the present invention have improved wear resistance and gas resistance while reconciling both characteristics, and thus longer life has been achieved.

Electrophotosensitive material

Disclosed are image forming apparatus [] which comprises removing a toner remained on the surface of the rotatable image carrier by cleaning means after going through developing means and transferring means; said cleaning means has an elastic blade and is contacted with the surface of the image carrier at a contact pressure within 8 to 20 g/cm, and a press-contact angle of the elastic blade of 12 to 30&#xb0;; and said image carrier is an organic photosensitive material having a photosensitive layer made of a binder resin containing an electric charge generating material and an electric charge transferring material; and image forming apparatus [], comprising a single-layer type photosensitive layer made of a binder resin containing an electric charge generating material, an electron transferring material and a hole transferring material, and the solid content of the binder resin is within 50 to 70 wt % of the whole solid content in the photosensitive layer and, a pair of paper transporting rollers are arranged on a path for transporting a transfer paper from paper feeding portion to transferring means, and a paper transporting roller at the side of the surface to be transferred among a pair of paper transporting rollers has cleaning means at the side of the surface to be transferred from the roller.

Image forming apparatus

An image forming device is disclosed which comprises an electrophotographic photoreceptor and a flash fixing means. The photoreceptor has a photoconductive layer formed on top of a support substrate, and the photoconductive layer contains a charge generating agent and a charge transport agent therein. The half maximum wavelength region of the charge transport agent's absorption peak is in a visual region that includes the wavelength region of the flash light when its intensity is 50% or greater of its maximum but does not include the wavelength region of the exposure light. This photoreceptor will not produce electrostatic irregularities even if light from the flash fixing means leaks thereon, and its sensitivity and its ability to be electrostatically charged will not decrease even if repeatedly used.

Electrophotographic photoreceptor and image forming device

A single-layer type electrophotosensitive material comprising a conductive substrate and a photosensitive layer made of a binder resin containing at least an electric charge generating material and a hole transferring material and an electron transferring material as an electric charge transferring material, which is formed on the conductive substrate, characterized in that the binder resin contains a polycarbonate resin having a repeating structural unit represented by the general formula &lsqb;1&rsqb; and the solid content of the hole transferring material and the electron transferring material is not less than 30% by weight and not more than 50% by weight relative to the entire solid content, exhibits good wear resistance with respect to the photosensitive layer and is also superior in durability.

Single-layer type electrophotosensitive material

Disclosed is a single-layer type electrophotosensitive material comprising a conductive substrate and a photosensitive layer made of a binder resin containing at least an electric charge generating material and an electric charge transferring material, which is formed on the conductive substrate, wherein an oxygen transmission rate of the binder resin is not more than 35 cc&middot;mm/m &middot;day&middot;atom, wherein it is preferred that a mobility at an electric field strength of 5&times;10 V/cm of the hole transferring material is not less than 5&times;10 cm /V/sec and a solid content of the electric charge transferring material is not less than 30% by weight and not more than 50% by weight based on the whole solid content; said electrophotosensitive material has good ozone resistance and does not cause defects such as image black belt due to lowering of the charge capability, an ozone of which is 5.0 ppm at most, and is also superior in sensitivity and wear resistance.
