An objective of the present invention is to provide a sliding member for sheet-shaped recording material detachment having superior resistance to abrasion and superior heat resistant rigidity, and either a seal ring for an automobile or a seal ring or a sliding member for an industrial gas compressor, having high mechanical strength while ensuring flexibility. The objective is achieved with a sliding member for sheet-shaped recording material detachment, and either a seal ring for an automobile or a seal ring or a sliding member for an industrial gas compressor, made from a resin composite comprising: as a first element, either an adhesive fluorocarbon resin (A) or a resin compound of the resin (A) and a fluorocarbon resin (B) which differs from the resin (A), which are in a volumetric ratio (AB) of 5/95 to 99/1; and as a second element, 0.5 to 99 volume % of a thermoplastic polyimide (C).

Sliding member for sheet-shaped recording material detachment, seal ring for automobile, and seal ring and sliding member for industrial gas compressor

A developing device includes a rotator that rotates around a shaft, and a bearing element that supports the shaft to a housing. A sliding element formed of a composite material that contains self-lubricating thermoplastic olefin resin as a base material is used as the bearing element. The sliding element formed of the composite material has at least a ratio of numerical values of 'Rockwell hardness'/'bending elastic modulus' in a range from 25 to 45, and provides a sliding surface of which a frictional coefficient is lower than that of the sliding element formed of the base material.
