(Fortune) -- Anne Mulcahy, Chairman and CEO of Xerox (Charts), ranks No. 2 on Fortune's 2006 list of 50 Most Powerful Women.

An emphasis on color copiers, digital presses, and systems that can copy, fax, print, and scan has helped the turnaround magician (aided by No. 27 Ursula Burns) continue to drive steady growth at the $15.7 billion company. Thanks to the iGen printer, which cost more than $1 billion to develop, Xerox is also a market leader in color commercial printing. In 2005 the company launched 49 new products.

By the key criteria Fortune uses in assembling its annual list - the size, importance, and health of each business in the global economy, and the momentum of each woman's career (along with her social and cultural influence) - there's no question that the power of women in the corporate sphere is rising.

Indeed, it could be called the year of the Most Powerful Woman CEO. The top seven positions on Fortune's 2006 Most Powerful Women list are held by CEOs. They include: Indra Nooyi of PepsiCo (Charts); Meg Whitman, eBay (Charts); Pat Woertz, ADM (Charts); Irene Rosenfeld, Kraft Foods (Charts); Brenda Barnes, Sara Lee (Charts); and Andrea Jung, Avon (Charts).
