1. An image forming system comprising:
an image forming apparatus to print an image on a sheet;
a sheet laminator including a heater to perform a lamination processing on a two-ply sheet with the sheet, which is conveyed from the image forming apparatus and inserted between two sheets of the two-ply sheet; and
circuitry to:
calculate a power consumed by the image forming apparatus during a first start-up period and a power consumed by the sheet laminator during a second start-up period;
control a timing, based on the calculation result, of a later one of the first start-up period or the second start-up period and control, based on the calculation result, a power supply during the later one of the first start-up period or the second start-up period;
perform a lamination print mode to cause the sheet laminator to perform the lamination processing on the sheet printed and conveyed from the image forming apparatus; and
perform a shift mode to:
start a power supply to the image forming apparatus and control an end of the power supply when the power supply reaches a first peak value and is stabilized during the first start-up period; and
start the power supply to the sheet laminator and control an end of the power supply when the power supply reaches a second peak value and is stabilized during the second start-up period shifted from the first start-up period.
