Image forming apparatus

摘要

In the present invention, upon return from a standby mode or sleep mode, image data is acquired as warming-up time estimate information for estimating the warming-up time to increase the temperature of a fixing belt to a target fixing temperature and, if the acquired image data is the data on a black-and-white image, control is performed to delay the heating start timing of the fixing belt.

主权项

1. An image forming apparatus comprising:
an image forming unit configured to form an image on a recording medium in accordance with input image information; a fixing unit configured to apply heat of a heated heating member to the image formed on the recording medium by the image forming unit so as to fix the image to the recording medium, thereby performing a heat fixing operation; an information acquiring unit configured to acquire warming-up time estimate information for estimating a warming-up time to increase a temperature of the heating member to a target fixing temperature, the warming-up time estimate information including information related to at least a type of the image and heat-accumulation state information of the fixing unit; and a heating control unit configured to control a heating start timing of the heating member based on the type of the image and a waiting time determined based on the heat-accumulation state information.
