Chris Massey claims ex-"Moesha" star, Shar Jackson, hits his 2-year-old daughter and even left her with a gash across her face ... which is why he's demanding court ordered protection.
Massey requested and was granted a temporary restraining order last week against Shar -- the mother of his baby mama, Cassilay Jackson. According to the docs, Chris dropped off his daughter in May to hang with mom and grandma for a few weeks.
When he picked her up ... Massey says, in the docs obtained by TMZ, she had a 4-inch "razor cut" across her forehead. He says his daughter, Mariah, blamed grandma Shar. Chris says he confronted Shar ... and claims she responded that she'd "do whatever she wants."
A judge granted Chris' request, ordering Shar stay at least 50 yards away from the kid. Shar's rep tells us, "Shar categorically denies all of this nonsense, as it it completely fabricated and from the mouth of a very troubled individual. Period."
