Abstract:
In an image forming apparatus, a recognition tag is an electronic tag in which recognition information is recorded in advance. A displacement mechanism holds a displacement portion at a first position so as to make a communication access from a tag reader to a recognition tag possible in a case where a replenishment unit is not attached to a unit attachment portion, and holds the displacement portion at a second position so as to make the communication access from the tag reader to the recognition tag impossible in a case where the replenishment unit is attached to the unit attachment portion. The state determining portion determines a state from among a unit attachment state, a unit non-attachment state, and an exceptional state based on information obtained via the tag reader.

Claim (Index 1):
An image forming apparatus comprising:\n at least one unit attachment portion to which a replenishment unit storing developer can be attached in a detachable manner; at least one antenna for short-distance wireless communication provided in correspondence with the unit attachment portion; a tag reader configured to, when the replenishment unit is attached to the unit attachment portion, read developer information concerning the developer from a unit tag by the short-distance wireless communication via the antenna, the unit tag being an electronic tag attached to the replenishment unit; at least one recognition tag provided in correspondence with the unit attachment portion, the recognition tag being an electronic tag in which recognition information is recorded in advance; a displacement mechanism configured to displace a displacement portion in response to an attachment or a detachment of the replenishment unit to or from the unit attachment portion, hold the displacement portion at a first position so as to make a communication access from the tag reader to the recognition tag possible in a case where the replenishment unit is not attached to the unit attachment portion, and hold the displacement portion at a second position so as to make the communication access from the tag reader to the recognition tag impossible in a case where the replenishment unit is attached to the unit attachment portion; and a state determining portion configured to determine a state from among a unit attachment state, a unit non-attachment state, and an exceptional state based on information obtained via the tag reader, the unit attachment state being a state where the developer information can be obtained from the unit tag, the unit non-attachment state being a state where the recognition information can be obtained from the recognition tag via the tag reader, the exceptional state being a state other than the unit attachment state and the unit non-attachment state.
