"I can confirm this report but we will have to appeal," university academic Mohammad Reza Jalaipour told AFP in a text message.
Lawyer Hojat Kermani, quoted by ILNA news agency, named four of the other reformists convicted as ex-deputy parliament speaker Mohammad Reza Khatami, former legislator Mohsen Safaie Farahani, Azar Mansouri, a member of an advisory panel for president Khatami during his 1997-2005 term, and Hossein Kashefi.
The lawyer said all five had been found guilty of "anti- regime propaganda", but he could not specify the charges against two other convicted reformists, ex-MPs Ali Shakouri Rad and Mohammad Naimipour, because he had not represented them.
The seven were leaders of the Islamic Iran Participation Front which authorities dissolved in 2010 following a wave of unprecedented protests against the re-election the previous year of hardline president Mahmoud Ahmadinejad.
