The England international has been regularly linked with a January move away from the Cottagers and could now be set for a deadline-day move to Loftus Road.
It was reported earlier that former Fulham manager Mark Hughes has made an approach to sign Zamora and the move has edged closer on Tuesday evening.
Zamora is currently undergoing a medical ahead of a potential move across west London, although it is understood Rangers are yet to agree to the striker's wage demands.
The R's would fork out a fee understood to be between £4million and £5million for Zamora, who would join fellow frontman Djibril Cisse at the Hoops.
Cisse, the 30-year-old former Liverpool and Sunderland player, has returned to England after a spell at Lazio for a fee in the region of 5million euros (£4.18million).
QPR have confirmed that Cisse has signed a two-and-a-half-year deal at Loftus Road and has been registered in time to make his QPR debut at Aston Villa tomorrow, subject to international clearance being received at least one hour before kick-off.
