The present invention provides an image processing apparatus and an image processing system which facilitate management against unauthorized use by creating a job log according to a usage status of a user. A creation section creates a different job log for each individual user. The job log has storage conditions of image data included in the job log set according to a storage level. The storage conditions are a color of an image, a resolution of the image data and whether or not necessary to create OCR data of the image data. To increase efficiency of a follow-up research by using such a job log, the storage level of the image data relating to the user having performed unauthorized use is raised.
