Bantams boss Peter Taylor told the club website: "Tom has done fine for us.
"He has had some great games and some not so great ones, but you could say the same about everybody. He is learning and will be a good player."
Canaries academy product Adeyemi has featured 17 times for Norwich and signed a new two-year deal in the summer.
City boss Paul Lambert added: "He's been playing really well for Bradford in his initial six months and I spoke with Peter Taylor recently who said he had done well.
"I'm sure it will benefit both him and the club that he will now spend the rest of the season with Bradford."
