'Most feared'
Mr Zhou, who is in his 70s, has not been seen in public for more than a year.
Analysts say the investigation against Mr Zhou allows Xi Jinping to consolidate his power base, remove people opposed to his reforms, and improve the image of the Communist Party.
Mr Zhou was previously also a member of China's top decision-making body, the Politburo Standing Committee.
For years, Mr Zhou was one of the most feared men in the country, the BBC's Asia analyst Charles Scanlon reports.
However, Mr Zhou has been systematically isolated for more than a year, with his former associates and family members brought down one by one by corruption allegations, our correspondent adds.
A Chinese minister has previously said that the investigation against Mr Zhou would take a long time to complete.
Mr Zhou had enjoyed a close working relationship with former Chongqing party chief Bo Xilai, who was sentenced to life imprisonment last year on bribery charges.
Bo's wife Gu Kailai was given a suspended death sentence in 2012 for the murder of British businessman Neil Heywood.
Bo's downfall was seen as the biggest political shake-up to hit China's ruling elite in decades, and revealed divisions at the top of the party over how the scandal should be handled.
