Abstract

An image forming apparatus forms a toner image of text on a recording sheet based on PDL data prescribing text data and one or more print conditions of thereof, and thermally fixes the toner image, and includes: condition acquisition unit analyzing the PDL data to acquire, as the conditions, one or more of character number, character spacing, and line spacing from the PDL data; judgment unit judging for each condition, by comparing the condition with reference value, the judgment indicating whether the condition is suitable for ensuring fixability of the toner image if thermally fixed at a temperature that is lower than predetermined temperature; and temperature control unit, when the judgment unit judges negatively for at least one condition, setting a fixing temperature for thermally fixing the toner image to the predetermined temperature, when the judgment unit judges affirmatively for all conditions, setting the fixing temperature to the lower temperature.
