The work is intended to draw attention to the benefits of migration, Banksy said.
The artist, who has never revealed his identity, donated elements of a recent installation to the camp for shelter.
In a rare public statement, Banksy said "We`re often led to believe migration is a drain on the country`s resources but Steve Jobs was the son of a Syrian migrant.
"Apple is the world`s most profitable company, it pays over $7bn (£4.6bn) a year in taxes - and it only exists because they allowed in a young man from Homs."
The work - painted on a concrete bridge in the camp - shows Jobs in his trademark black polo neck and round glasses. He appears to be carrying a bin bag full of his possessions, as if he were a migrant.
Another unrelated graffiti reads: "Nobody deserves to live this way!"
In pictures posted on the artist`s website, the work can be seen near tents and adjacent to another piece of graffiti which reads: "Nobody deserves to live this way!"
The camp in Calais is home to about 7,000 migrants and refugees, the majority from Syria, Afghanistan and Eritrea.
While at the camp, Banksy painted several other pieces, including one based on Theodore Gericault`s famous painting Raft of the Medusa, but depicting refugees waving towards a luxury yacht.
Banksy recently donated wood and other structural elements from his "bemusement park" installation Dismaland to the Calais camp to help build shelters.
The installation, in Weston-Super-Mare, closed in September.
