PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of detecting an amount of a coating agent and the like attached to an image carrier to correct transfer voltage, and thereby executing normal transfer.SOLUTION: An image forming apparatus includes control means 202 provided with transfer current storage means 401 for storing a current value detected by transfer current detection means 203d when voltage is applied by transfer voltage application means 203c. The control means 202 determines that an amount of attached matters attached to an image carrier 102 is at a predetermined amount or more when the current value stored in the transfer current storage means 401 gradually increases and the increased current value exceeds a predetermined current value. |
