Akinde has made just one league start for City since joining from Ebbsfleet in September 2008.
"There was a lot of interest in John and he's opted for this loan move to Dagenham," Robins boss Keith Millen told the club website.
"Hopefully he'll go there and get some first team games under his belt. He needs to give his career a kick start."
Akindi cost City £140,000 when he made the switch from non-league Ebbsfleet, where he scored 12 goals in 34 games.
He has since had loan spells at Wycombe and Brentford before heading to the Robins' city rivals.
