An image forming apparatus includes an image bearing member, a developing apparatus, a driving device, an airflow space portion, a duct, and, a drawing fan. A driving-force transmission member, the driving device and the airflow space portion are disposed on a side on which a developer container faces the image bearing member. The driving-force transmission member, the driving device, the duct and the drawing fan are disposed on one end side of a developing rotary member in a rotation-axis direction of the developing rotary member. The duct is disposed underneath the developer container, formed from the side on which the developer container faces the image bearing member to a side opposite to the side on which the developer container faces the image bearing member. The drawing fan is disposed on the side opposite to the side on which the developer container faces the image bearing member.

A conduction mechanism includes: a conductive bearing that rotatably supports a rotary shaft; a non-conductive axial positioner that has a cylinder externally fitted to the bearing; and a contact terminal attached to an outer circumferential surface side of the cylinder. The cylinder has a slit, and the contact terminal has an abutment piece that is exposed to an inner circumferential surface side of the cylinder from the slit and abuts an outer circumferential surface of the bearing.

Systems and methods relating to accurate Channel State Information (CSI) measurements for a License Assisted Secondary Cell (LA SCell) are disclosed herein. In some embodiments, a wireless device enabled to operate in a cellular communications network according to a carrier aggregation scheme using both a licensed frequency band and an unlicensed frequency band operates to determine whether a Channel State Information Reference Symbol (CSI-RS) transmission from a LA SCell of the wireless device is present in a subframe, where the LA SCell is in an unlicensed frequency band. The wireless device further operates to process a CSI-RS measurement for the LA SCell for the subframe upon determining that a CSI-RS transmission from the LA SCell is present in the subframe and refrain from processing a CSI-RS measurement for the LA SCell for the subframe upon determining that a CSI-RS transmission from the LA SCell is not present in the subframe.

An image forming apparatus includes a controller, a drive unit, a developer bearing member, a regulation blade, and a sheet member. During non-image forming, the controller executes a control mode for controlling the drive unit to rotatably drive the developer bearing member in a second direction opposite to a first direction, and then rotatably drive the developer bearing member in the first direction. A portion above a horizontal line passing through a tip of the regulation blade out of the sheet member is disposed in a moving path of a developer born by the developer bearing member when the drive unit rotatably drives the developer bearing member in the second direction in the control mode, and is not disposed in the moving path of the developer born by the developer bearing member when the drive unit rotatably drives the developer bearing member in the first direction during image forming.

A developing apparatus including: a first chamber including a first conveyance member conveying developer in a first direction; a second chamber including a second conveyance member having a conveyance portion conveying the developer in a second direction opposite to the first direction and a return conveyance portion provided downstream of the conveyance portion in the second direction to convey the developer in the first direction; a first partition wall provided between the first chamber and the second chamber to form a first communication portion and a second communication portion to form a circulation route; and a bearing member configured to rotatably support the second conveyance member and including: a discharge port provided downstream of the return conveyance portion; and a second partition wall extending from the bearing member in the first direction to cover a portion of the return conveyance portion confronting the first communication portion.

A developing device includes a developer conveyer, a bearing, a flange, and a developer mover. The developer conveyer is rotatable and configured to convey a developer. The bearing rotatably supports a support shaft of the developer conveyer. The flange is disposed at an end portion of the developer conveyor to regulate a movement of the developer in an axial direction of the developer conveyer. The developer mover is disposed on a surface of the flange facing the bearing and configured to move the developer that enters between the flange and the bearing.

If a user is not familiar with the operation for the developer supply container, the rotating operation for the developer supply container may be insufficient, so that developer supply container does not reach a predetermined operating position, with the result of abnormal developer supply. by increasing a rotation load of a second gear 6 which is in an operable connection with a drive gear member 12 of the developer receiving apparatus 10 by a function of a locking member 7, the developer supply container 1 mounted to the developer receiving apparatus 10 is rotated toward the supply position. After the developer supply container 1 rotates to the supply position, the locking by the locking member 7 is released, by which the rotation load applied to the second gear 6 is reduced, so that drive transmission, thereafter, to the feeding member 4 for developer supply is smooth.

An image forming apparatus includes an image bearing member, a transfer rotating body, a feeding means and a control means that controls a feeding speed of a recording material in a feeding portion at the feeding means. Wherein a first timing is a timing during when a rear end of the recording material with respect to a feeding direction passes through a transferring portion and a second timing is a timing when the rear end of the recording material is separated from the image bearing member after passing through the transferring portion, the control means can control the feeding means for one recording material so that a feeding speed of the recording material at the second timing in the feeding portion becomes faster than that of at the first timing in the feeding portion.

Systems and methods relating to accurate Channel State Information (CSI) measurements for a License Assisted Secondary Cell (LA SCell) are disclosed herein. An exemplary user equipment enabled includes a transceiver, at least one processor, and memory containing instructions executable by the at least one processor whereby the user equipment operates to detect whether a downlink control information (DCI) message indicating that a Channel State Information Reference Symbol (CSI-RS) transmission from an LA SCell of the user equipment is present in a subframe. When the user equipment detects that the DCI message indicates that a CSI-RS transmission from the LA SCell is present in the subframe, it processes a CSI-RS measurement. When the user equipment detects that the DCI message does not indicate that a CSI-RS transmission from the LA SCell is present in the subframe, it refrains from processing the CSI-RS measurement.

A conduction mechanism includes: a conductive bearing that rotatably supports a rotary shaft; a non-conductive axial positioner that has a cylinder externally fitted to the bearing; and a contact terminal attached to an outer circumferential surface side of the cylinder. The cylinder has a slit, and the contact terminal has an abutment piece that is exposed to an inner circumferential surface side of the cylinder from the slit and abuts an outer circumferential surface of the bearing.
