Charlton land Reading striker Lita
The 23-year-old will spend 28 days at The Valley under former Royals boss Alan Pardew with the loan expiring on March 31.
Lita missed the start of the season with a freak injury after damaging a leg muscle as he stretched in bed after waking up.
Manager Steve Coppell believes both club and player will benefit from the former Bristol City player's spell in south London.
He told the club's official website: "Leroy has been frustrated at his lack of first-team action recently, so this loan move will be a perfect way for him to retain match sharpness at the highest level of Championship competition."
