Abstract: 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.

Abstract: A connection unit receives image data to be printed and image information on a type of the image data from an external device. A pseudo-halftone processing unit converts the image data into pseudo-halftone image data. When the image information received from the external device indicates that the type of the image data is a point-of-purchase advertising image, the pseudo-halftone processing unit performs a pseudo-halftone processing on the image data at a quantization level of three or more bits on a pixel and takes a growth order causing all pixels in a low-density area to grow averagely.

Abstract: An image forming apparatus includes a fixing unit and a re-heating unit. The fixing unit fixes a toner image on a recording medium by applying heat to the toner image with a first glossiness level. The re-heating unit re-heats the toner image, fixed on the recording medium by the fixing unit, to set a second glossiness level lower than the first glossiness level.
