Abstract
An image forming apparatus includes: a first toner consumption amount calculation section which calculates a toner consumption amount based on a toner replenishment operation; a coefficient calculation section which calculates a coefficient by dividing the toner consumption amount calculated by the first toner consumption amount calculation section by a number of pixels; a second toner consumption amount calculation section which calculates the toner consumption amount by multiplying the number of pixels by the coefficient calculated by the coefficient calculation section; and a near depletion detector which detects near depletion when a total toner consumption amount exceeds a near depletion threshold value. When a difference between a coefficient reference value and the coefficient calculated by the coefficient calculation section is at most an allowable value, the near depletion detector changes the near depletion threshold value to a changed near depletion threshold value which is smaller than the near depletion threshold value.
