Heating transport device, fixing device, and image forming apparatus

摘要

Provided is a heating transport device, including a heating transport roll around which a recording medium to which a toner image is transferred is wound, and that transports the recording medium while heating the toner image to a temperature higher than or equal to a melting temperature of toner, and a cooling roll that forms a nip with the heating transport roll, transports the recording medium, and cools the recording medium such that the temperature of the recording medium is lower than or equal to a heat deformation temperature of the recording medium at a position at which the recording medium separates from the heating transport roll.

主权项

1. A fixing device, comprising:
a heating transport device including:
(i) a heating transport roll around which a recording medium to which a toner image is transferred is wound, and that transports the recording medium while heating the toner image to a temperature higher than or equal to a melting temperature of toner; and(ii) a cooling roll that forms a nip with the heating transport roll, transports the recording medium, and cools the recording medium such that the temperature of the recording medium is lower than or equal to a heat deformation temperature of the recording medium at a position at which the recording medium separates from the heating transport roll; and a fixing roll that fixes the toner image to the recording medium on an upstream side of the nip of the recording medium in a state of the recording medium being wound around the heating transport roll of the heating transport device.
