  In the hybrid kT-factorization formula, one initial-state parton momentum is
space-like and carries non-vanishing transverse components, while the other is
on-shell. We promote this factorization formula to next-to-leading order.
Studying the partonic cross section, we identify all soft and collinear
divergencies in the real and virtual contribution, and recognize that all
non-cancelling ones can be attributed to PDF evolution, evolution kernel, and
target impact factors. In result, we construct a framework that may be used to
compute NLO impact factors in general. In particular, we recover known
expressions for inclusive NLO quark-and gluon impact factor corrections.
