Ephraim heads to London Road looking to play regular first-team football having found opportunities limited at his parent club.
He told the club's official website: "It was time for me to get out and play a bit of first team football. I have played at this level with Leeds United and Charlton, so I know what to expect. The team like to play attacking football, so I am looking forward to it.
"I have played at London Road before and was on the losing side and know exactly how loud the home fans can be. I can play in a number of positions, in midfield or behind the strikers, but obviously I am just looking to play.
"It is up to me to impress in training."
