Abstract: An example image forming apparatus may include a memory storing computer executable instructions and a processor. The processor may, by executing the computer executable instructions stored in the memory, determine whether a toner cartridge mounted in the image forming apparatus is genuine, and when it is determined that the toner cartridge is non-genuine, deactivate a user-defined application installed in the image forming apparatus.
