The 22-year-old forward initially joined the Gills on loan for a month at the start of January, but he will now stay in League One for the remainder of 2014-15.
He has had an instant impact for the Kent club with three goals in four appearances.
Marquis also scored once in 13 League Two appearances for Cheltenham Town earlier this season.
