Reports suggested the Chelsea forward would be loaned out to a second tier club in January but Robinson insists the Blues are delighted with Bamford's stay in Milton Keynes.
"I've spoken with Chelsea and that is fabricated nonsense," Robinson told MK News.
"Nothing has come from Chelsea at all, they don't know where the story has come from.
"Chelsea are very happy at Patrick being here and they're ecstatic at the fact he's coming here and scoring goals.
"Whether people are trying to upset the applecart with us or their agent I don't know, but Patrick knew nothing of it and Chelsea have said nothing.
"That can put fans' minds at rest and quash any rumours."
