This paper provides the analysis of resolved sources. After a validated process of data reduction and calibration, we perform intensive simulations to optimize the source extraction, measure the confusion noise (σc=45mJy), and give the photometric and astrometric accuracies. 196 galaxies with flux S>3σc are detected in the area of 3.89 square degrees. Counts of sources with flux S>4σc present a steep slope of 3.3±0.6 on a differential ``logN-logS'' plot between 180 and 500mJy. As a consequence, the confusion level is high and will impact dramatically on future IR deep surveys. This strong evolution, compared with a slope of 2.5 from Euclidian geometry, is in line with models implying a strongly evolving Luminous Infrared Galaxy population. The resolved sources account for less than 10% of the Cosmic Infrared Background at 170µm, which is expected to be resolved into sources in the 1 to 10mJy range. File Summary:
