PROBLEM TO BE SOLVED: To provide a siloxy-imine functionalized rubbery polymer, which is useful for a filler-reinforced rubber composition and exhibits good reinforcing characteristics and filler dispersing effect. SOLUTION: The method for producing the functionalized rubbery polymer includes polymerizing a conjugated diene monomer using an organolithium compound as an initiator in a hydrocarbon solvent. Next, an active terminal end of the polymer is reacted with a functionalized terminating agent, represented by formula (1) (wherein R represents a 6C-18C aryl or substituted aryl group, or a 3C-18C heterocycle or heteroaryl; R<SP>1</SP>and R<SP>2</SP>each independently represents a 1C-18C group selected from an alkyl, a cycloalkyl, an allyl, and an aryl; X is an integer from 1 to 20; and Y is an integer from 1 to 3).
