Most are facing charges that include possession and distribution of child pornography.
The bus drivers charged - Schreiner, 28, of Williamstown, and Nortez, 28, of Egg Harbor Township - worked for Sheppard Bus Co. in Mays Landing.
The company removed Schreiner and Nortez from their positions, said spokesman Manny Cabegin. He said that he was unaware of any connection between students and the alleged crimes and that Sheppard is cooperating with authorities. He declined to comment further.
Authorities said Schreiner, who also was charged with endangering the welfare of a child, shared explicit pictures with a boy he met online. He was arrested July 11.
Nortez was arrested June 25 and charged with possession and distribution of child pornography.
Others charged include Fink, 41, of Cherry Hill, who allegedly had more than 750 images and videos of child pornography on an external hard drive, and Johnson, 46, of Pemberton Township, who was charged with possession and distribution of child pornography.
They also include Michael Parker, 55, of Pennsauken, who tried deleting more than 200 explicit images when detectives knocked on his door, the Attorney General's Office said. Parker also had pictures of clothed children from First Presbyterian Church of Merchantville, where he tried to become a youth minister, authorities said.
Elie Honig, director of the New Jersey Division of Criminal Justice, said in a statement that the operations to take down child predators were "critical."
"Viewing these vile images is a serious crime in itself, because it motivates those who sexually exploit children to create child pornography and it revictimizes the children involved," Honig said.
The remaining men charged include: Michael Van Culin, 30, of Monroeville; Thomas Pirretti, 31, of Flemington; Walter Javier Vibanco, 47, of Lower Township; Daniel Allen Corda, 46, of Bellmawr; Jerrell Harris, 28, of Elizabeth; Matthew Hems, 23, of Tabernacle; Arnold M. Kay, 74, of Linden; Jorge Geovani Lopez-Betancourt, 34, of Trenton; and Raymond Purkis III, 48, of Montgomery Township.
