Latin Modern Math font has slanted integrals:

XITS Math have default slanted integrals as well as optional upright

Both fonts use the new OpenType MATH table and thus need an application
that support it for proper math typesetting, namely MS Office 2007+,
XeTeX and LuaTeX.

STIX fonts also provide both:

XITS Math supports the mathematical variants using variation sequences
that are listed here:

Many TeX math fonts have slanted integrals.
