1. An image forming apparatus comprising:
a developing cartridge including:
a casing configured to accommodate developing agent therein;
a storage medium having an electrical contact surface; and
a developing roller movable together with the casing;
a photosensitive drum contactable with the developing roller;
an electrical connector contactable with the electrical contact surface;
a separation mechanism configured to move the developing roller between a first position in which the developing roller is separated from the photosensitive drum in a state where the electrical connector is in contact with the electrical contact surface and a second position in which the developing roller is in contact with the photosensitive drum in a state where the electrical connector is in contact with the electrical contact surface; and
a controller configured to control the separation mechanism, the controller configured to communicate with the storage medium via the electrical connector,
the controller being configured to perform:
moving, by controlling the separation mechanism, the developing roller between the first position and the second position; and
communicating with the storage medium via the electrical connector in a state where the developing roller is in the first position.
