IMAGE FORMING APPARATUS, IMAGE FORMING METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM STORING CONTROL PROGRAM

摘要

An image forming apparatus includes an image forming section to form a toner image and transfer the toner image to a recording medium and a fixing section to heat the recording medium transferred with the toner image and further an image analyzing section to extract a density value or a size value of an imaging object included in an image, and a temperature determining section to determine a minimum fixing temperature based on the density value or size value of the imaging object included in a page image. The temperature determining section determines the minimum fixing temperature to be lower when a highest one of the density values is lower than when the highest value is higher or determines the minimum fixing temperature to be lower when a largest one of the size values is smaller than when the largest size value is larger.

主权项

1. An image forming apparatus including:
an image forming section configured to form a toner image based on image data and transfer the formed toner image to a recording medium; a fixing section configured to heat the recording medium to which the toner image has been transferred in the image forming section to fix the toner image; an image analyzing section configured to extract, from the image data of the image to be formed in the image forming section, at least one of a density value and a size value of each of imaging objects included in the image; and a temperature determining section configured to determine a minimum fixing temperature of the fixing section for the recording medium transferred with a page image which is an image corresponding to one page of the recording medium to be formed in the image forming section, the minimum fixing temperature being determined based on the extracted density values or size values of the imaging objects included in the page image, the temperature determining section is configured to perform, based on the density value or the size value of each of the imaging objects in the page image, at least one of setting the minimum fixing temperature to be lower when a highest one of the density values is lower than when the highest one of the density values is higher, and setting the minimum fixing temperature to be lower when a largest one of the size values is smaller than when the largest one of the size values is larger.
