A developing roller 20 included in a developing device 1 and a photoconductor drum 100 are located adjacently to or in contact with each other. A toner absorbed on the surface of the developing roller 20 moves to the photoconductor drum 100 by an electrostatic force, whereby an electrostatic latent image is formed. The developing roller 20 has on the surface thereof a developing sleeve 30. On the surface of a base 31 of the developing sleeve 30, an electroless nickel plating layer 32 is formed. Further, on the surface of the nickel plating layer 32, a nickel oxide coating 33 is formed. The nickel oxide coating 33 passivates the surface of the developing sleeve 30 to thereby suppress the tendency of the toner charge to dissipate as a result of nickel plating treatment, thus permitting the toner charge holding property to be maintained in a favorable state.

A light emitting device includes a resin molded body having a circular or an oval recessed section at the center suppresses generation of cracks. The device is provided with a light emitting element, a first resin molded body having a plurality of outer surfaces, and a recessed section at the center. First and second leads are electrically connected to the light emitting element, and a second resin molded body is applied in the recessed section. The light emitting element is placed on the first lead, and the surface of the second resin molded resin forms a light emitting surface. A gate notch is formed on an extended line of a normal line on one point on a circular cross-section of the recessed section in the normal line direction.

Disclosed is a core-shell microparticle (10) which is produced by heating a mixture of a crosslinked microparticle (11) having an alkoxyamine group (12) and a monomer to 100 to 180° C. to cause graft polymerization. The crosslinked microparticle (11) is produced by allowing a seed particle to absorb a monomer mixture comprising 15 to 99% by mass of a crosslinkable monomer and 1 to 85% by weight of a monomer having an alkoxyamine group, and then adding a polymerization initiator to the resulting product to cause the polymerization of the monomer mixture.
摘要:
A resin molding device includes a lead plate and a first resin molding member. The lead plate includes patterns. Each of the patterns includes a base, a plurality of lead pairs; and a lead connection portion. Each of the lead pairs includes a first lead and a second lead. The first resin molding member is integrally formed with the base and the lead pairs. The first resin molding member defines a recessed portion at a mounting side surface on the base where a light emitting device is to be mounted. The recessed portion is formed to open upwardly and to have a side surface. The lead pairs are partially exposed at a bottom surface area of the recessed portion. The first lead or the second lead is capable of mounting a protection device thereon such that the protection device is covered by the first resin molding member.
