Image forming apparatus having detector configured to detect information regarding cartridge attached thereto

摘要

An image forming apparatus is provided, which includes a displacement member disposed at a cartridge and configured to move from a position where the displacement member receives a driving force from an apparatus main body to a position where the displacement member does not receive the driving force. The apparatus also includes a movable member disposed at the apparatus main body, the movable member moving in response to movement of the displacement member, so as to move a first electrode between a position where the first electrode contacts a second electrode and a position where the first electrode is spaced apart from the second electrode. Also, the apparatus includes a detector detecting information about the cartridge attached to the apparatus main body based on a conduction state between the first electrode and the second electrode.

1. An image forming apparatus comprising:
an apparatus main body; a cartridge configured to be detachably attached to the apparatus main body, the cartridge comprising:
an electrical component; anda conductive section electrically connected with the electrical component; a power feeder disposed at the apparatus main body and configured to contact the conductive section and apply a voltage to the electrical component; a first electrode disposed at the apparatus main body and electrically connected with the power feeder; a second electrode disposed at the apparatus main body and configured to be in contact with and spaced apart from the first electrode; a displacement member disposed at the cartridge and configured to move from a position where the displacement member is allowed to receive a driving force from the apparatus main body to a different position where the displacement member is not allowed to receive the driving force from the apparatus main body; a movable member disposed at the apparatus main body, the movable member being configured to move in response to movement of the displacement member, so as to move the first electrode between a contact position where the first electrode contacts the second electrode and a non-contact position where the first electrode is spaced apart from the second electrode; and a detector configured to detect information about the cartridge attached to the apparatus main body based on a conduction state between the first electrode and the second electrode, wherein the movable member is configured to contact the displacement member at a contact portion thereof and to move in response to receipt of a force via the contact portion of the movable member with the displacement member, and wherein the apparatus main body comprises a terminal member comprising:
the power feeder;the first electrode; anda terminal-side spring configured to press the movable member against the displacement member.
