摘要： A sheet processing device includes a rotator, a first nipper, a conveyor, a second nipper, a detector, a memory, and circuitry. The rotator winds a two-ply sheet around the rotator to generate a winding circumferential difference between two sheets of the two-ply sheet to separate the two sheets. The detector detects an abnormal condition, in which a gap greater than a given interval is not formed between the two sheets around the rotator. The memory stores a detection result as the abnormal condition. The circuitry is to increase a nipping force of the second nipper with the rotator, and increase the nipping force in a present sheet processing to be greater than a previous nipping force of the second nipper in a previous sheet processing, when the memory stores the detection of the abnormal condition in the previous sheet processing, to wind the two sheets around the rotator.
