Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
