Abstract
An image forming apparatus includes an image bearing member for bearing an image of toner and a charging member contactable to the image bearing member to charge the image bearing member. The charging member is adapted to receive a voltage and the toner has a melt index of not less than 0.5 g/10 min. In the apparatus, EQU P/(V.times.L).ltoreq.50J/m.sup.2 where v is a movement speed of the image bearing member when the image bearing member is charged by the charging member (m/sec), L is an effective charging length of the charging member, measured in a direction perpendicular to the movement direction of the image bearing member (m), and P is an amount of electric power consumed by the charging member (W).
