Image processing apparatus, non-transitory computer readable medium, and method for controlling image processing apparatus

A non-transitory computer readable medium storing a program causing a computer to execute a process for controlling an image processing apparatus including a processor and a first cache memory used by the processor, the process comprising:

• storing, in the first cache memory, pixel data items arranged in a line in a main-scanning direction, the pixel data items being stored in units of a plurality of lines;
• executing a shift process on a plurality of pixel data items stored in the first cache memory for each of pixel blocks to prevent deviation in a sub-scanning direction in forming an image, the pixel block being composed of a predetermined number of pixel data items and serving as a processing unit;
• and
• performing a storing process in which among the pixel data items in the plurality of lines that are stored in the first cache memory, pixel data items to be stored in an area with consecutive addresses in the memory as a result of the shift process are collectively stored in the memory.
