An image forming apparatus includes a toner-layer filling-rate lowering unit that causes a toner layer of toner images to be formed on an image carrier so that the toner layer has sufficient optical transparency for exposing and the toner-layer filling rate is set relatively low; and a toner rolling rate adjusting unit that rolls the toner images at a predetermined toner rolling rate in accordance with the toner-layer filling rate when the toner images are transferred to the transferring/fixing unit.

A corona charger includes a case provided in the vicinity of a device to be charged. The case includes an opening facing the device, a discharge electrode, a first charging region, and a second charging region. The discharge electrode provided inside the case and supplied with a voltage so as to generate a corona discharge charges a surface of the device from the opening by supplying the corona discharge to the surface. The first charging region includes no grid electrode at a position upstream of the opening in a surface moving direction of the device. The second charging region includes a grid electrode to which a predetermined voltage is applied at a position downstream of the opening. The voltage applied to the discharge electrode is an alternating current (AC) voltage superimposed on a direct current (DC) voltage.

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^.

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.
