Angle-resolved photoelectron spectroscopy measurements were made in the Ce $$3d$$$$rightarrow$$4$$f$$ resonance energy region for the paramagnetic state of CeRu$$_2$$Si$$_2$$, CeRu$$_2$$(Si$$_{0.82}$$Ge$$_{0.18}$$)$$_2$$ and LaRu$$_2$$Si$$_2$$ to investigate a variation of band structures around the quantum critical point. The results indicate that the Ce $$4f$$ electrons in the paramagnetic state have an itinerant character and participate in the formation of energy bands both in CeRu$$_2$$Si$$_2$$ and CeRu$$_2$$(Si$$_{0.82}$$Ge$$_{0.18}$$)$$_2$$, and the change of the band structures in the paramagnetic states should be continuous around the quantum critical point of the CeRu$$_2$$(Si$$_{1-x}$$Ge$$_{x}$$)$$_2$$ system.
