摘要： A transfer-fixing device (66) includes a transfer-fixing member (27), a pressing member (68), a heating device (67), and a temperature equalizer (85). The transfer-fixing member carries the toner image. The pressing member presses against the transfer-fixing member to form a nip portion to which the recording medium is conveyed. The heating device heats the transfer-fixing surface of the recording medium conveyed toward the nip portion. The temperature equalizer equalizes a temperature distribution of a surface of the transfer-fixing member in a width direction of the transfer-fixing member after the surface of the transfer-fixing member passes through the nip portion.

摘要： A transfer-fixing device (66; 66A; 66B; 66C) transfers and fixes a toner image onto a transfer-fixing surface of a recording medium, and includes a transfer-fixing member (27), a pressing member (68), a heating member (67; 67X; 67Y), and a temperature equalization member (85). The transfer-fixing member carries the toner image. The pressing member pressingly contacts the transfer-fixing member to form a nip between the pressing member and the transfer-fixing member through which the recording medium passes. The heating member heats the transfer-fixing surface of the recording medium conveyed toward the nip so that the recording medium reaches the nip before a temperature of a back surface opposite the transfer-fixing surface of the recording medium increases. The temperature equalization member equalizes temperature distribution on a surface of the transfer-fixing member in a width direction of the transfer-fixing member perpendicular to a conveyance direction of the recording medium, after the surface of the transfer-fixing member passes the nip.

摘要： An image forming apparatus includes an image carrying member (10), an intermediate transfer member (21), a charging member, a transfer mechanism, a discharging member, a direct current voltage source, and a direct current voltage controller. The intermediate transfer member is deposited at a position facing and in contact with the image carrying member rotatably carrying a toner image on a rotating surface, and receives the toner image therefrom during a first transfer operation. The charging member applies a charge to the intermediate transfer member to cause an electric field around a region where the image carrying member and the intermediate transfer member contact with each other, where the electric field generates a force for initiating the first transfer operation. The transfer mechanism (30) performs a second transfer operation for transferring the toner image from the intermediate transfer member to a transfer sheet. The discharging member (50) performs a discharging operation for discharging the charge remaining on the intermediate transfer member with contacting the intermediate transfer member after a completion of the second transfer operation. The direct current voltage source applies a direct current voltage to the discharging member to cause the discharging member to perform the discharging operation. The direct current voltage controller controls the direct current voltage in accordance with a volume resistivity of the intermediate transfer member.
