Anderson was found to have breached a clause relating to ''inappropriate and deliberate physical contact between players in the course of play'', the ICC said in a news release today.
The England player twice nudged against batsman Runako Morton during his brief stay at the crease and, after the West Indian was dismissed, ran towards him to start a verbal confrontation.
Match referee Mike Procter found Morton not guilty of a clause relating to offensive language or gestures.
''I concluded Runako Morton was the victim of James Anderson's aggression rather than guilty of bad behaviour,'' said Procter.
England and West Indies are level at 1-1 going into the third and final match of the series at Nottingham on Saturday.
