ABSTRACT:
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 roller1includes a shaft member2including a hollow cylindrical body or a solid cylindrical body of a resin containing an electrically conducting agent and a resin layer4. The resin layer4is 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.
