Abstract: An image heating apparatus includes a rotatable belt, a driving source, a heating portion, a heat shielding member, a shielding member moving mechanism, and a controller. The controller is configured to control the moving mechanism so that the shielding member is in a shielding position and rotation of the belt is at rest in a stand-by state in which the image heating apparatus waits for input of an image forming signal for forming the image.

Abstract: An image forming apparatus includes an image forming portion 10 for forming an image on a sheet 16 by using a developer 15 including toner and a curable agent curable by ultraviolet radiation, a feeding belt 14 for feeding the sheet on which the image is formed by the image forming portion 10, an infrared irradiating portion 13 for irradiating, with infrared radiation, the image on the sheet 16 fed by the feeding belt 14, an ultraviolet irradiating portion 12 for irradiating, with the ultraviolet radiation, the image on the sheet having been irradiated with the infrared radiation by the infrared irradiating portion 13, and a controller 50 for controlling operations of the feeding belt 14 and the infrared irradiating portion 13. The controller 50 causes the infrared irradiating portion 13 to irradiate the feeding belt 14 with the infrared radiation while causing the feeding belt 14 to rotate in a stand-by state in which the controller 50 waits for an execution instruction of an image forming operation in a state in which the image forming operation is capable of being started.
