Jones has been linked with the top job at Swansea City.
Martinez said: "It's nothing new. Graeme and I have been working together since 2007 and it's good when you get those links because it means people still remember the work that you did at a previous club.
"But Graeme is fully focused at Everton and it's not even a question.
"The only thing that matters is the results at Everton and there's not going to be any changes in that respect."
