Abstract

An image forming method and image forming apparatus in which a toner image formed on an image carrier (11) through steps of discharging, main charging, exposure and development is transferred to a recording medium (S) and then fixed as an image using flash light. The image forming apparatus (10) has a secondary charger (17) for secondarily charging the image carrier to have the same polarity as a polarity given by a main charger (12) and a surface potential larger in absolute value than a surface potential given by the main charger.
