Bloomfield operates under a Special Charter granted under an Act of the New Jersey Legislature. The township is governed by a mayor and a six member Township Council. The mayor and three council members are elected at-large, and three members are elected from each of three wards, with all positions chosen on a partisan basis as part of the November general election. Council members are elected to three-year terms of office on a staggered basis, with the three at-large seats (and the mayoral seat) up for election together and the three ward seat coming up for election two years later. Bloomfield's charter retains most of the characteristics of the Town form, with additional powers delegated to an administrator.
As of 2017, the Mayor of Bloomfield is Democrat Michael J. Venezia, whose term of office ends December 31, 2019. Members of the Bloomfield Township Council are:
