Abstract:
An image formation system, comprising:paper transport means for transporting paper along a paper transport passage;image formation means for forming an image on an image carry belt;image sense means for sensing a position of the image formed on the image carry belt;transfer means for transferring the image formed on the image carry belt to the paper transported by said paper transport means;paper passage sense means for sensing paper passage on the paper transport passage, said paper passage sense means being disposed upstream from a position where the image is transferred by said transfer means; andcontrol means for controlling paper transport speed of said paper transport means based on the sense results of said image sense means and said paper passage sense means,wherein said control means controls the paper transport speed of said paper transport means by one of: adjusting timing at which the paper transport speed of said paper transport means is changed from a high-speed level faster than process speed at image transfer time to the process speed, andvarying the paper transport speed of said paper transport means between a high-speed level faster than process speed at image transfer time and a low-speed level slower than the process speed.
