An image forming apparatus includes: a photoconductor having a photoconductive layer on an outer surface thereof; a charging portion that charges the photoconductor; a developing portion that develops a latent image formed on the photoconductor; a transfer portion that transfers a developed image; current detectors respectively provided to the charging portion, the developing portion, and the transfer portion to detect currents respectively flowing from the charging portion, the developing portion, and the transfer portion to the photoconductor; an integrating portion that calculates a charge amount by integrating the currents detected by the current detectors over a given period of time; and a layer thickness calculating portion that calculates a thickness of the photoconductive layer based on the charge amount.
