摘要：
An image forming apparatus comprises an image information obtainer that obtains image information, a gradation sequence processor that applies multiple types of gradation sequence processing to the image information, and a toner image formation device that forms a toner image based on the image information. A fixing device is provided to fix the toner image onto a recording medium in a fixing process. A temperature controller is also provided to change a start-up temperature of the fixing device before the fixing process. The start-up temperature is changed in accordance with inclusion of a halftone process and a type of the gradation sequence processing applied to the image information.
