A developing device includes a housing having an opening in a wall, a developing roller having a hollow interior portion, a magnetic pole structure disposed within the hollow interior portion of the roller, a gap forming member, and a blocking member. The gap forming member is located within, and spaced from, the housing at a location downstream, in the rotation direction of the developing roller, of the opening in the wall of the housing, forms a first gap with respect to the developing roller and forms a second gap with respect to the housing. The gap forming member has a first side facing the opening in the wall of the housing and a second side spaced inwardly of the housing, from the first wall. The blocking member is located in the first gap and at one of the first and second sides of the gap forming member.

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 method of attaching a regulating blade made of resin to an attachment portion of a development frame which is made of resin and includes the attachment portion for attaching the regulating blade includes applying an adhesive to the attachment portion, applying a hardening accelerator to the regulating blade, and attaching the regulating blade to the attachment portion via the adhesive applied to the attachment portion and the hardening accelerator applied to the regulating blade. The regulating blade is disposed opposite to and not in contact with a development rotary member configured to bear and convey a developer toward a position at which an electrostatic image formed on an image bearing member is developed, and configured to regulate an amount of the developer to be borne on the development rotary member.

A developer container includes a plurality of components combined together to form a space to store a developer. The plurality of components includes a first component and a second component. The developer container further includes a sealant to bond the first component and the second component, and a position regulator to regulate relative positions of the first component and the second component so as to maintain a distance between an adhesion portion of the first component and an adhesion portion of the second component.

There is provided a manufacturing method of manufacturing a cartridge by using a cartridge having a rotator, a frame that supports the rotator, an elastic member that is provided in a concave portion formed in the frame along a rotation axis direction of the rotator, and a sheet member that has one end fixed to the elastic member and the other end abutting on the rotator along the rotation axis direction of the rotator, and the manufacturing method includes: detaching the rotator from the frame; detaching the sheet member from the frame; detaching the elastic member from the frame; and attaching another sheet member to the frame via an adhesive member that is attached to an adhesive member attachment portion formed in the concave portion of the frame.

A developing device according to an embodiment includes a housing, a developing roller, a gap forming member, and a guide section. The gap forming member forms a first gap between the gap forming member and the developing roller. The gap forming member forms a second gap between the gap forming member and the housing. The second gap includes an upstream side opening on a rotating direction upstream side of the developing roller. The guide section directs an air current discharged from the second gap via the upstream side opening to the first gap. A relation of H1/H2<5 is satisfied, where H1 is a minimum interval between the developing roller and the gap forming member in the first gap and H2 is a minimum interval between the housing and the gap forming member in the second gap when viewed from an axial direction of the developing roller.

Systems and methods relating to accurate Channel State Information (CSI) measurements for a License Assisted Secondary Cell (LA SCell) are disclosed herein. A wireless device operates 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 CSI Reference Symbol (CSI-RS) transmission from an LA SCell is present in a subframe, where the LA SCell is in an unlicensed frequency band. Upon determining that a CSI-RS transmission is present in the subframe, the wireless device performs a first type of interference measurement on configured CSI Interference Measurement (CSI-IM) resources in the subframe. Upon determining that a CSI-RS transmission is not present in the subframe, the wireless device performs a second type of interference measurement on the configured CSI-IM resources in the subframe. Related methods and storage media are also described.

In one aspect an apparatus (200) for use in an electrographic printer includes a tray (260) defining a cavity (262), the tray having an internal surface, and an ink developer electrode (250) disposed in the cavity for developing an ink. There is a first layer (264) disposed on the internal surface, the first layer comprising a dielectric material, and a second layer (266) disposed on the first layer, the second layer adhering to the first layer and being resistant to the adhesion of ink. In another aspect manufacturing such apparatus comprises applying respective polymer precursor compositions to form the two layers and crosslinking the second polymer composition.

A method of attaching a regulating blade made of resin to an attachment portion of a development frame which is made of resin and includes the attachment portion for attaching the regulating blade includes applying an adhesive to the attachment portion, applying a hardening accelerator to the regulating blade, and attaching the regulating blade to the attachment portion via the adhesive applied to the attachment portion and the hardening accelerator applied to the regulating blade. The regulating blade is disposed opposite to and not in contact with a development rotary member configured to bear and convey a developer toward a position at which an electrostatic image formed on an image bearing member is developed, and configured to regulate an amount of the developer to be borne on the development rotary member.
