• and
• a first hardware processor configured to measure time from a predetermined timing until the detection sensor detects the recording material,
• the information processing apparatus comprising:
• a second hardware processor configured to receive time data measured by the first hardware processor, and
• wherein the second hardware processor is further configured to classify a plurality of received time data into a first group and a second group in accordance with a length of time, and determine whether slipping is caused by the feeding rotation member by using the time data included in the first group and the time data included in the second group.
