Abstract
A color image printing apparatus has a plurality of positioning mechanisms each of which selectively positions a corresponding photoconductive drum at an operative position and a non-operative position. A controlling section selectively controls the positioning mechanisms in a first operation mode or in a second operation mode according to the color detected in the color plane by the color detecting section. The first operation mode is a mode where the controlling section causes a positioning mechanism corresponding to the color detected by the color detecting section to the operative position, and the positioning mechanism remains at the operative position throughout the job once it is brought to the operative position. The second operation mode is a mode where if only black is detected in the first page of a job then a photoconductive drum corresponding to black is brought to the operative position, and if any one of yellow, magenta, and cyan black is detected in a subsequent page, the controlling section causes all of the positioning mechanisms to be brought to their operative positions.
