Image processing apparatus and image forming apparatus

An image forming apparatus comprising:

• a controller for generating expanded image data;
• a local bus connected with the controller;
• a plurality of independent generic buses which are independent from each other;
• a plurality of image processing sections, each of which is respectively connected to each of the plurality of generic buses, for executing image processing of the expanded image data to generate processed image data;
• a plurality of bridges, each of which connects the local bus with each of the plurality of generic buses;
• a memory section for storing at least one of the expanded image data and the processed image data;
• and
• an image forming section connected to any one of the plurality of image processing sections,
• wherein the plurality of image processing sections share execution of image processing of the expanded image data generated by the controller, and the memory section memorizes the processed image data.
