Image processing apparatus and image forming apparatus

An image processing apparatus, comprising:

• an image forming instructing section which notifies an image forming section, which is capable of performing a first printing processing of performing image forming with use of a plurality of colors including at least one chromatic color and a second printing processing of performing image forming with use of only black color, a printing type processing requested to be performed among the first printing processing and the second printing processing;
• a data obtaining section which obtains pixel data from a plurality of pixels constituting an image;
• an operating section for inputting designated color data indicating color;
• a pixel data extracting section which extracts pixel data of colors, except for a designated color indicated by the designated color data inputted through the operating section, from pixel data obtained by the data obtaining section;
• and
• a printing type selecting section which selects a printing type from among the first printing processing and the second printing processing based on each pixel data extracted by the pixel data extracting section, wherein
• the image forming instructing section notifies the printing type selected by the printing type selecting section as the type of printing processing requested to be performed.
