摘要： An ultraviolet curable resin composition includes (A) an ultraviolet curable resin, (B) an epoxy compound having at least two epoxy groups in one molecule, (C) a photopolymerization initiator and (D) a diluent. The ultraviolet curable resin (A) is obtained by the steps of polymerizing an ethylenically unsaturated monomer component containing (a) an ethylenically unsaturated monomer having epoxy group and (b) a compound having at least two ethylenically unsaturated groups in one molecule to prepare a copolymer, reacting the copolymer with (c) an ethylenically unsaturated monomer having carboxyl group to prepare a chemical intermediate, and reacting the chemical intermediate with (d) one of saturated and unsaturated polybasic acid anhydrides. This resin composition will be preferably used to prepare a photo solder resist ink developable with diluted alkaline aqueous solution.

摘要： An amount-of-remaining-toner detecting device includes: a toner housing portion in which a toner bottle is housed, the toner bottle having a bottle body that is cylindrical and in which toner is housed, and a cap that is attached to one end of the bottle body in an axial direction of the bottle body and from which the toner housed in the bottle body is discharged; and circuitry configured to detect an amount of remaining toner in the toner bottle housed in the toner housing portion. The toner housing portion includes a first pair of electrodes facing each other with the bottle body interposed between the first pair of electrodes, and a second pair of electrodes facing each other with the bottle body interposed between the second pair of electrodes, at respective positions closer to the cap than the first pair of electrodes are. The circuitry detects the amount of remaining toner in the bottle body, based on at least one of a capacitance value between the first pair of electrodes or a capacitance value between the second pair of electrodes.

摘要： A developing device includes a developer bearer to carry, by rotation, developer to a developing range, a casing including a developer container to contain the developer and housing the developer bearer, a gap retainer adjacent to the developer container and downstream from the developing range in a rotation direction of the developer bearer, an opposing wall opposing an end face of the gap retainer in an axial direction of the developer bearer, a first seal disposed between the end face of the gap retainer and the opposing wall, and a contact portion disposed adjacent to an end portion of the gap retainer in the axial direction of the developer bearer. The gap retainer secures a predetermined gap between the developer bearer and the gap retainer. The contact portion contacts, via a second seal, the gap retainer in a direction intersecting the axial direction of the developer bearer.

摘要： A powder amount detector includes a vibration plate secured to a powder container to contain powder and positioned at a predetermined position in a stationary state, a shaft to rotate inside the powder container, a contact member attached to the shaft, a vibration detector to detect vibration of the vibration plate, and a detection result processor to determine an amount of the powder in the powder container according to a detection result generated by the vibration detector. The contact member is to flip the vibration plate to cause the vibration plate to repeat elastic deformation and reversion to vibrate. The contact member is to exit an area opposed to the vibration plate after the contact member flips the vibration plate by the time the vibration plate returns to the predetermined position.

摘要： A toner cartridge includes a toner container to store toner and two rotary agitation members to rotate to agitate toner in the toner container. The toner container has two arc-shaped portions adjacent to each other at an inner bottom wall of the toner container. The two rotary agitation members has edges to rotate along the two arc-shaped portions with rotation phases thereof shifted from each other. The two rotary agitation members are placed with rotation trajectories thereof partially overlapping each other.

摘要： A powder container includes a powder chamber for containing powder for forming images, a powder outlet formed in a face of the powder container, and a shutter assembly to open and close the powder outlet and including first and second shutters. The first shutter is movable between a sealing position to close the powder outlet and an open position to open the powder outlet and includes a pressed member to cancel retention of the first shutter at the sealing position. The second shutter includes a pressing projection that interferes with the pressed member of the first shutter and is movable between a shielding position to cover the pressed member without interference between the pressing projection and the pressed member and a releasing position to press the pressed member with the pressing projection.

摘要： A developing device, process cartridge, and image forming apparatus, have transport members with screw and shaft portions, transporting developer within the device in a longitudinal direction of a circulation path. A supply supplies new carrier to the device. A discharge aperture in a transport path wall of one transport member discharges developer outside the circulation path, when a surface of the developer transported by the one transport member exceeds a predetermined height. A bias path aperture in the transport path wall upstream of the discharge aperture has a bottom at a higher level than a bottom of the discharge aperture, and diverts developer at a level higher than the bottom of the discharge aperture to another transport member. An area in the longitudinal direction of the one transport member has no screw portion, and the discharge aperture is disposed opposite the area and has a length smaller than the area.
