An image heating apparatus has a heater to heat an image formed on a recording material. The heater has a plurality of heat generating elements. A control portion controls electrical power supplied to the plurality of heat generating elements. The control portion respectively sets a heating amount with respect to a region in which an image is formed and a heating amount with respect to a region in which an image is not formed in a single sheet of the recording material. The control portion is further configured to at least set the heating amount with respect to the region in which the image is not formed when the recording material is heavy paper to become less than the heating amount with respect to the region in which the image is not formed when the recording material is plain paper.

An image forming apparatus includes a toner image supporting section and a medium transfer section. The toner image supporting section includes first and second toner image supporting member that support first and second toner images at first and second linear speeds, respectively. The medium transfer section transfers, onto a medium, the first and second toner images respectively supported by the first and second toner image supporting members, to thereby cause the first and second toner images to be superimposed on each other. The following conditional expression (1) is satisfied when the medium transfer section transfers the first and second toner images onto the medium,
(Vd1Vt1)/(Vt1>(Vd2Vt2)/Vt2(1)
where Vd1 is the first linear speed, Vt1 is a first conveyance speed of the medium, Vd2 is the second linear speed, and Vt2 is a second conveyance speed of the medium.

A printing apparatus includes a transport unit for transporting a continuous sheet, a printing unit for printing by discharging ink to the continuous sheet, and a drying unit for drying the ink deposited on the continuous sheet. The drying unit includes a first heater unit for heating a printed surface of the continuous sheet and a second heater unit for heating the opposite surface of the continuous sheet to the printed surface. The first heater unit includes a plurality of first heaters that are disposed at the same position in a transport direction and that are arranged in width directions. The second heater unit includes a plurality of second heaters that are disposed at a position superposed on the first heater unit in the transport direction and that are disposed at positions between adjacent ones of first heating elements of the first heaters in the width directions.

In an image forming method according to the present invention, an image is formed by removing residual charge from the image on an image recording medium. The image forming method includes formation of an image for forming a toner image by fixing a toner on the image recording medium and application of voltage from a voltage applier, the voltage having a polarity reverse to a polarity of a surface potential of the toner image. The toner includes toner base particles and an external additive. The toner base particles include a crystalline polyester resin.
