An image forming apparatus has an image forming information processor to process image forming information and an image forming unit to form an image on a recording medium by forming a toner image using colored-toner and a toner image using glossy toner based on the image forming information processed by the image forming information processor. The image forming unit forms a glossy image on the recording medium based on glossy toner image forming information, in which the glossy image is formable on the recording medium using the colored-toner toner image alone, or a glossy image is formed on the recording medium by forming a colored-toner toner image using colored-toner based on the colored-toner image forming information, and then forming the glossy toner image on the colored-toner toner image as a top layer of the glossy image based on the glossy toner image forming information.

A main vector: m^=(mx, my) and a sub-vector: s^=(sx, sy) determining cyclic structure of a basic matrix are defined, and a positional vector for a pixel configuring the basic matrix Pi^=(Pix, Piy) is defined, where the suffix i denotes an i-th pixel configuring the basic matrix. Then, the pixels configuring the basic matrix are arranged in such a manner as to satisfy the cyclic structure, and transformation of Pi^→Pi^+km^+ls^ is carried out where k and l are arbitrary integers, and may be negative values. Then a new shape of the basic matrix is obtained with Pi^+km^+ls^ as a new pixel positional vector Pi^.

摘要:
An image forming apparatus is disclosed, including a fixing device and a sheet storing member. The fixing device performs both tentative fixing and regular fixing. In at least one embodiment, the fixing device performs tentative fixing for tentatively fixing a toner image on a recording sheet. Further, the fixing device performs regular fixing for further fixing the tentatively fixed toner image by contacting a gloss sheet onto the tentatively fixed toner image on the recording sheet. The sheet storing member temporarily stores the recording sheet bearing the tentatively fixed toner image before the recording sheet is sent to the fixing device for the further fixing.

A rotary-body driving-force transmitting mechanism transmits a driving force from a driving-force source to a rotary body. A rotary-inertial-body driving-force transmitting mechanism transmits the driving force to a rotary inertial body that suppresses a velocity fluctuation in the rotary body. A rotational velocity shift mechanism shifts the rotational velocity. The rotary inertial body, the rotary-body driving-force transmitting mechanism, and the rotary-inertial-body driving-force transmitting mechanism are provided coaxially with a rotary shaft of the rotary body. A satellite frictional gear mechanism is used as the rotational velocity shift mechanism.

An image forming apparatus includes a photoconductive element including a conductive support rotatably supported and a charge injection layer and a surface protection layer sequentially laminated on the conductive support. A charger includes a conductive body for injecting, when a preselected voltage is applied thereto, a charge in the charge injection layer in contact with the surface protection layer. A writing unit exposes the charged surface of the photoconductive element imagewise to thereby locally vary the potential deposited on the photoconductive element and electrostatically form a latent image. A developing unit develops the latent image to thereby produce a corresponding toner image. The toner image is transferred from the photoconductive element to a recording medium. Assuming that the charge injection layer has a thickness of D micrometers, and that the potential deposited on the surface of the photoconductive element by the conductive member is V volts in absolute value, then a ratio V/D is confined in a preselected range that does not contaminate the background of the photoconductive element.
