Image forming apparatus

An image forming apparatus comprising:

• an apparatus body comprising a controller;
• a photoconductor unit comprising a photoconductor and attached to the apparatus body so as to be drawable from the apparatus body;
• a guide member provided in the apparatus body and configured to guide the photoconductor unit with respect to the apparatus body;
• a developing cartridge configured to be attachable to and detachable from an attachment portion provided in the photoconductor unit, the developing cartridge comprising:
• a casing configured to accommodate developer;
• a developing roller configured to develop an electrostatic latent image on the photoconductor by using the developer;
• and
• a storage medium configured to store information about the developing cartridge;
• a first contact portion provided in the photoconductor unit and configured to be electrically connected to the storage medium in a state in which the developing cartridge is attached to the photoconductor unit;
• and
• a second contact portion provided in the apparatus body, electrically connected to the controller, and configured to be in contact with the first contact portion in a state in which the photoconductor unit is attached to the apparatus body,
• wherein the photoconductor unit is configured to, in a case of attaching the photoconductor unit to the apparatus body, move from a first position to a second position while being guided by the guide member and then move from the second position to a third position, the first position being a position where the developing cartridge is attachable to and detachable from the attachment portion, the third position being a position which is below the second position and in which an image forming operation on a recording medium is executable,
• wherein a first direction from the first position toward the second position is a horizontal direction or a direction whose inclination with respect to the horizontal direction is smaller than inclination of a second direction from the second position toward the third position with respect to the horizontal direction, and
• wherein at least one of the first contact portion and the second contact portion is capable of being displaced such that engagement between the first contact portion and the second contact portion is performed while the photoconductor unit moves in the first direction by being guided by the guide member, and the engagement is maintained while the photoconductor unit moves from the second position to the third position.
