  In KEK, two syn­chro­tron light sources have been op­er­ated. One is the 2.5 GeV Pho­ton Fac­tory stor­age ring (PF-ring) and the other is the 6.5 GeV Pho­ton Fac­tory ad­vanced ring (PF-AR). In this paper, pre­sent op­er­a­tional sta­tus and re­cent R&D ac­tiv­i­ties such as fast local bump sys­tem for he­lic­ity switch­ing un­du­la­tor, hy­brid in­jec­tion sys­tem, pulsed-sex­tu­pole in­jec­tion, etc. Futher­more, up­grade plan to­wards the top-up in­jec­tion of 6.5 GeV PF-AR ring is un­der­way. Con­struc­tion of the straight in­jec­tion tun­nel from linac to PF-AR will be started next fis­cal year. De­sign de­tail and strat­egy for the in­jec­tion scheme will be re­ported.
