Abstract
In an image forming apparatus, a first electric pathway connects a charging portion and a power supply unit, a second electric pathway is formed in the photoconductor unit and connects the first electric pathway and the photoconductor. An electrical component is disposed on the second electric pathway and has predetermined electrical property in accordance with the type of the photoconductor unit. A current detection portion is configured to detect current flowing through the second electric pathway when a detection voltage is applied on the first electric pathway. A determination processing portion is configured to determine the type of the photoconductor unit and existence of usage of the photoconductor unit, based on a current value detected by the current detection portion. The blocking portion is configured to block the second electric pathway after determination by the determination processing portion.
