The longitudinal container body has a first end and a second end distal to the first end in a length direction of the container body. The held portion is attached to the first end of the container body and configured to be detachably attached to the toner-container holder. The held portion includes a toner outlet for discharging the toner. The electric component electrically communicates with a component in the main body to detect whether the toner container is operatively set in the toner-container holder. The electric component is attached to the held portion such that when the held portion is attached to the toner-container holder the electric component is located above the toner outlet with respect to a vertical direction. ## Claims ### Claim 1 A toner container for detachably attaching to a toner-container holder of an image forming apparatus, the toner container comprising: a longitudinal container body for containing toner, the container body having a first end and a second end distal to the first end in a length direction of the container body, the first end including an opening; an end attached to the first end of the container body and configured to be detachably attached to the toner-container holder, the end including a toner outlet for discharging the toner from the container body, the end including: a first cylindrical portion; and a second cylindrical portion which has a smaller diameter than a diameter of the first cylindrical portion, the first and second cylindrical portions having a common central axis; and an electric component, attached to the second cylindrical portion, that electrically communicates with a component in the image forming apparatus to detect whether the toner container is operatively set in the toner-container holder, the electric component being attached to the end such that when the end is attached to the toner-container holder, the electric component is located above the toner outlet with respect to a vertical direction. ### Claim 2 (depends on 1) The toner container according to claim 1, wherein the electric component includes a memory that stores therein at least one of information related to toner contained in the container body and information related to recycling. ### Claim 3 (depends on 2) The toner container according to claim 2, wherein the information related to the toner includes at least one of information of toner color, production number, and production date. ### Claim 4 (depends on 1) The toner container according to claim 1, wherein the electronic component includes a memory that stores information related to the toner container; and a communicating unit that performs non-contact communication with a communication circuit provided in the toner-container holder while the toner container is held by the toner-container holder. ### Claim 5 (depends on 4) The toner container according to claim 4, wherein the electric component is provided on a surface of the second cylindrical portion, the surface being orthogonal to a direction of attachment/detachment of the toner container to/from the toner-container holder, and the electric component is located at a position opposing the communication circuit when the toner container is attached to the toner-container holder. ### Claim 6 (depends on 1) The toner container according to claim 1, wherein the electronic component is attached to the second cylindrical portion so as to be located more forward than the toner outlet while the toner container is held by the toner-container holder. ### Claim 7 (depends on 6) The toner container according to claim 6, wherein the second cylindrical portion further includes a protrusion portion protruding in an attachment direction of the toner container to the toner-container holder, and the electronic component is provided on the protrusion portion and on a plane that is orthogonal to the attachment direction. ### Claim 8 (depends on 7) The toner container according to claim 7, wherein the protrusion portion further includes a wall portion around the electronic component. ### Claim 9 (depends on 1) The toner container according to claim 1, wherein the container body contains toner therein. ### Claim 10 (depends on 9) The toner container according to claim 9, wherein a ratio of filling volume/entire volume of the toner contained in the container body is 0.7 or less. ### Claim 11 (depends on 9) The toner container according to claim 9, wherein the container body further contain carrier. ### Claim 12 (depends on 9) The toner container according to claim 9, wherein a weight ratio of the carrier contained in the container body ranges from 3 wt % to 20 wt % with respect to the weight of the carrier and the toner. ### Claim 13 (depends on 1) The toner container according to claim 1, wherein the electric component includes an ID chip. ### Claim 14 (depends on 1) The toner container according to claim 1, wherein the container body is configured to rotate, and to feed the toner contained therein toward the opening along with rotation thereof. ### Claim 15 (depends on 14) The toner container according to claim 14, wherein the container body includes a gear provided on a circumferential surface thereof, and the gear transmits rotation drive force to the container body. ### Claim 16 (depends on 15) The toner container according to claim 15, wherein the first cylindrical portion covers at least part of the gear. ### Claim 17 (depends on 14) The toner container according to claim 14, wherein the container body has a spiral-shaped protrusion on an inner circumference thereof. ### Claim 18 (depends on 1) The toner container according to claim 1, wherein the container body has a conveying member that conveys the toner contained therein toward the opening. ### Claim 19 (depends on 18) The toner container according to claim 18, wherein the conveying member includes a coil that is configured to be rotatable. ### Claim 20 (depends on 18) The toner container according to claim 18, wherein the conveying member has a plated-form member that is configured to be movable in a longitudinal direction of the container body. ### Claim 21 (depends on 1) The toner container according to claim 1, further comprising: a nozzle hole to receive a nozzle of the image forming apparatus which is parallel to a length of the longitudinal container body, the nozzle to receive the toner from the toner outlet while the nozzle is in the nozzle hole, wherein the electric component and the nozzle hole are provided on an orthogonal plane of the second cylindrical portion. ### Claim 22 (depends on 1) The toner container according to claim 1, wherein: the common central axis penetrates the electrical component. ### Claim 23 (depends on 22) The toner container according to claim 22, wherein: the electrical component is mounted to a front surface of the second cylindrical portion which is perpendicular to the common central axis.
