摘要： There are provided a developing roller capable of making useless a drying line in the formation of a resin layer and using a carbon-based electrically conducting agent for giving an electrical conductivity to the resin layer as well as an imaging apparatus using the same. The developing roller 1 comprises a shaft member 2 constituted with a hollow cylindrical body or a solid cylindrical body of a resin containing an electrically conducting agent and a resin layer 4. The resin layer 4 is made from a ultraviolet-curing type resin containing a carbon-based electrically conducting agent and a ultraviolet initiator, in which the ultraviolet initiator has a maximum wavelength in a ultraviolet absorption wavelength region of not less than 400 nm. The resin layer 4 may be made from an electron beam curing type resin containing the electrically conducting agent.
摘要翻译：提供了一种显影辊，其能够在树脂层的形成中使干燥线无用，并且使用用于向树脂层赋予导电性的碳基导电剂以及使用该干燥线的成像装置。显影辊1包括由中空圆柱体或包含导电剂和树脂层4的树脂的实心圆柱体构成的轴构件2.树脂层4由含有碳的紫外线固化型树脂制成的紫外线引发剂和紫外线引发剂，紫外线引发剂的紫外吸收波长区域的波长区域最大为400nm以上。树脂层4可以由含有导电剂的电子束固化型树脂制成。

摘要： A lock nut of the present invention comprises a metal nut base body and a synthetic resin portion, an internally threaded portion having a diameter smaller than that of an internally threaded portion of the nut base body and extending therefrom being formed in a cap-like portion formed at one end of the nut base body. This lock nut can prevent the occurrence of looseness after the lock nut has been fastened.
摘要翻译：本发明的锁紧螺母包括金属螺母基体和合成树脂部分，内螺纹部分的直径小于螺母基体的内螺纹部分的直径，并从其延伸形成为帽状部分形成在螺母基体的一端。该锁紧螺母可以防止锁紧螺母固定后发生松动。

摘要： A developing roller includes an ultraviolet-curing type resin layer and using a carbon-based electrically conducting agent for giving an electrical conductivity to the resin layer, as well as an imaging apparatus using the same. The developing roller 1 includes a shaft member 2 including a hollow cylindrical body or a solid cylindrical body of a resin containing an electrically conducting agent and a resin layer 4. The resin layer 4 is made of a resin having fine particles dispersed therein, wherein a ratio a/b of average particle size of fine particles a to a total thickness of resin layers b is greater than 2.0 and less than or equal to 5.0.
