Abstract:
1. An image forming apparatus, comprising: an image reader that reads an image of a document, a tint block detector that detects whether or not a tint block is formed on the document based on image data obtained by a reading operation of the image reader and that detects the color of the tint block based on the image data when the tint block is detected, an image forming section including a plurality of developers and adapted to form an image on a recording medium using one or more of the developers based on the image data, an image formation controller that causes the image forming section to perform a monochromatic image forming operation using a single developer as an image forming operation relating to the tint block when the tint block was detected by the tint block detector, and a mode setter alternatively setting a normal image forming mode for performing a normal image forming operation by the image forming section and a developer suppressing mode for suppressing the consumption of the developers required for an image forming operation based on the same image data as compared with the normal image forming mode, wherein: the image formation controller causes the image forming section to perform the monochromatic image forming operation as an image forming operation relating to the entire image of the document when the tint block detector detects the tint block and the color of the tint block detected by the tint block detector is a mixed color of the colors of at least two of the respective developers in the case of being set the developer suppressing mode by the mode setter.
