Although Bahman Borojeni has experienced various methods in different periods of his career, has always been considered as a portrait master artist. Borojeni got his diploma from the Tehran Academy of Fine Arts. In the conservatory, he was taught miniature and design by professors such as Hossein Behzad and Shokooh Riazi. Then in 1962 he was admitted to the Faculty of Decorative Arts and graduated with bachelor's and master's degrees in painting from this university. He left for France in the late 1960s to pursue a Phd in Islamic art at the Sorbonne University. He became a member of the Faculty of Decorative Arts and was the dean of this university for a while. Borojeni was also one of the founders of Tarbiat Modares University.
His first solo exhibition was held in 1964 at the Faculty of Decorative Arts. His works have been exhibited in countries such as Norway, Belgium, Iran, France, Japan, and the United States. Borujeni's first appearance at the auctions dates back to November 2011 at the Christie's Auction House. 
In the first period of his career, he followed the academic path and focused on anatomy and composition. Influenced by his French masters, he later introduced modernist construction techniques to his work. For a long time he focused on engraving. Then he started to create paintings with very large dimensions and was supported by Hossein Kazemi. After that, he had experiences in nature painting and later created paintings stacked with various figures. 

“A lot of human beings become visible with a faded highlight in a gray space,” said Javad Mojabi about the paintings of Borojeni. “This crowd is sometimes reminiscent of a kind of miniature engraving, and at one time Broglovar's mass-production and Gustav's designs from the period of the Divine Comedy. They are - I suppose - created under the influence of a kind of metaphysical viewpoint, as if they are on an infinite journey in mystical behavior; "And of course they have a little similarity to Alkhas’s works." 
Borojeni's paintings are usually abstract and figurative. bold colors, and brisk brushstrokes are some of the characteristics of his works. Pakbaz writes about Borujeni's recent works: "Since the 1990s, he has changed his previous painting routine and depicts themes from “Parisian life” with smooth lines and bright spots. Some of his paintings are reproduced in the form of postcards or posters.”
