摘要： A heating apparatus includes a body and a holder removably placed inside the body. The holder removably holds a heating object. A receiver removably holds the holder. A heater heats the heating object held by the holder held by the receiver. A mover moves one of the receiver and the heater vertically relative to another one of the receiver and the heater to a non-contact heating position where the heating object is isolated from the heater.

摘要： There is provided an image forming apparatus including a configuration in which a voltage of a polarity opposite to a toner charging polarity is applied. In the image forming apparatus, a guide region of a pre-transfer guide is located on a photosensitive drum side with respect to a common tangent line of a photosensitive drum and a development roller to reduce contamination of the pre-transfer guide and prevent contamination of recording materials.

摘要： Apparatus is described which, in use, applies a thin film of a wetting agent, such as water or a water-based solution, onto paper or other print medium before applying a liquid toner. The wetting agent is applied at a predetermined distance from an image transfer area. The wetting agent acts to promote adhesion of the liquid toner to the print medium. The adhesion of the liquid toner to the print medium is further improved by supplying the wetting agent at a temperature higher than room temperature.

摘要： An image forming apparatus includes: an image carrier carrying a toner image; a transfer unit disposed to contact the image carrier and transferring the toner image carried on the image carrier to a recording medium; and a gap forming unit that forms a gap between the image carrier and the transfer unit when one or more regions of the recording medium are positioned between the image carrier and the transfer unit. The one or more regions include at least one of a leading end and a trailing end of the recording medium. The image forming apparatus further includes an electric charge applying unit disposed on an upstream side of the transfer unit and applies electric charges to the one or more regions of the recording medium. The electric charges have an opposite polarity to a charging polarity of a toner which forms the toner image.

摘要： An image forming apparatus includes a toner image carrier on which a toner image is formed, a transfer unit that transfers the toner image onto a continuous sheet of paper, a fixing machine that fixes the transferred toner image onto the continuous sheet of paper, a sheet transport unit that transports the continuous sheet of paper through a transport path passing through a transfer position and a fixing position, and an electric charge supply unit that is disposed at a position at which the continuous sheet of paper is placed between the toner image carrier and the electric charge supply unit and that supplies electric charge having an orientation, in which transfer by the transfer unit is prevented, to a toner image present in a region on the toner image carrier, which is out of the continuous sheet of paper.

摘要： An image forming apparatus includes an image carrier that carries an electrostatic latent image; a developing unit that develops the electrostatic latent image using a toner; an intermediate transfer body onto which toner image is transferred; a secondary transfer member that comes in contact with a surface of the intermediate transfer body; a power supply that outputs a voltage for transferring the toner image on the intermediate transfer body onto a recording member; and a protective agent supply unit that applies a protective agent including zinc stearate and boron nitride onto a surface of the image carrier. The voltage is alternatively switched in a transfer direction and an opposite direction. The voltage in the transfer direction enables transfer of the toner image from the intermediate transfer body to the recording member, and the voltage in the opposite direction has polarity opposite to polarity of the voltage in the transfer direction.
