To provide an image formation device for transferring data for forming images in synchronization with movement of an image formation executing section capable of maintaining image forming quality regardless of quantity of data for transmitting and not needlessly slowing down processing speed.

The image formation device for executing image formation based on the image data has the executing section for executing the image formation in a predetermined range at the same speed, a processing section for obtaining the image data by a unit of the image data corresponding to respective divided areas constituted by dividing the predetermined range in synchronization with the movement of the executing section and transmitting signals after processing to the executing section after executing predetermined processing to the obtained image data, and a control section for controlling the speed of the executing section according to the size of the image data corresponding to the respective divided areas obtained by the processing section.
