Ishikawa Toyonobu (1711 - July 1, 1785) was a Japanese ukiyo-e print artist. He is sometimes said to have been the same person as Nishimura Shigenobu, a contemporary ukiyo-e artist and student of Nishimura Shigenaga about whom very little is known. A pupil of Nishimura Shigenaga, Toyonobu produced many monochrome 'lacquer prints' (urushi-e) which reflected the influence of Okumura Masanobu as well. Many of these were yakusha-e (actor prints) and bijinga (images of beautiful women), including images of standing courtesans, whose faces conveyed an impassivity typical of the works of the Kaigetsudi school. Later in his career, Toyonobu became one of the leading producers of color prints, chiefly benizuri-e ('rose prints'), but stopped producing ukiyo-e shortly after Suzuki Harunobu pioneered the full-color print (nishiki-e) in 1765.
