Abstract: An image forming apparatus includes an image forming unit that forms, when forming an image with a white toner on a colored recording medium, a base toner layer and a white toner layer in an overlapped manner such that the base toner layer is inserted between the white toner layer and the colored recording medium, and a fixing unit that fixes the base toner layer and the white toner layer that are formed by the image forming unit on the recording medium.

Abstract: A developing cartridge includes a developing roller with a shaft, a housing with a wall portion, a developing electrode, a first contact portion, a second contact portion, and a connecting portion. The developing electrode includes a first contact portion contacting the shaft and has a first surface against which an apparatus electrode of an image forming apparatus body slides, a second contact portion disposed next to the first contact portion, and a second surface configured to contact an electrode of the image forming apparatus. The connecting portion includes a first inclined surface connecting the first surface and the second surface with each other and being contiguous with the first surface. The first inclined surface is inclined toward the second contact portion from the first contact portion such that the first inclined surface extends in a direction away from the wall portion.

Abstract: An image forming apparatus includes an image bearing member, a transfer device, a first charging device, a static elimination device, a second charging device, a light exposure device, and a development device. The transfer device transfers a developer image of a first polarity onto a recording medium from the image bearing member by receiving a transfer bias of a second polarity. The first charging device charges a region of the image bearing member that has undergone transfer to the first polarity by receiving a first charging bias of the first polarity. An absolute value of the first charging bias is greater during charging of a first region of the image bearing member than during charging of a second region of the image bearing member. The first region includes a trailing end contact section. The second region does not include the trailing end contact section or a leading end contact section.

Abstract: A first developer image is overprinted on a second developer image printed on a medium. A user inputs, through an inputting section, a magnification ratio or a reduction ratio of at least one of the first developer image and the second developer material image that should be printed. The magnification and the reduction ratios are applied vertically and horizontally substantially. A data parser performs parsing of print data. A magnification/reduction section produces the first image and the second image from the print data based on a result of the parsing. The first image is subjected to a variable magnification process. An image forming section transfers and fixes the first developer material image onto the medium after the variable magnification process, and then transfers and fixes the second developer material image on the medium so that the first and second developer material images are placed one over the other.

Abstract: An image forming apparatus is provided. A first cleaning unit is configured to collect a particle deposited on an object. An applying unit is configured to apply a voltage to the first cleaning unit. A first detector is configured to detect a first current flowing between the first cleaning unit and the object. A controller is configured to control the applying unit. When the detected first current becomes equal to or greater than a first predetermined value, the controller controls the applying unit to reduce the voltage applied to the first cleaning unit so as to make the first current smaller than the first predetermined value.

Abstract: A printer specific stream of bits is received, before or while the printing of a print job, and translated into a pixel count specific to the print job and indicative of the anticipated toner usage for the print job. This pixel count then is added to a global pixel count indicative of toner usage of jobs printed since a global pixel counter was reset.
