PROBLEM TO BE SOLVED: To provide an image forming apparatus that suppresses an increase in rotational torque of an image carrier.SOLUTION: An image forming apparatus includes an image carrier, charging means, electrostatic charge image forming means, developing means, transfer means, cleaning means including a cleaning blade, and lubricant supply means. The developing means uses an electrostatic charge image developer including a toner containing toner particles having a volume average particle diameter of 3.0 μm or more and less than 5.0 μm, silica particles externally added to the toner particles and having a number average particle diameter of 40 nm or more and 110 nm or less and a shape factor SF2 of 130 or more and 180 or less, and polishing agent particles externally added to the toner particles. |
