A conveyance apparatus to determine a correction value for conveyance, the conveyance apparatus comprising: a first conveyance unit configured to convey a sheet in a conveyance direction; and a second conveyance unit disposed at a position downstream of the conveyance direction from the first conveyance unit and configured to convey the sheet in the conveyance direction, wherein, in a case where the sheet is conveyed only by the first conveyance unit, a first conveyance amount is obtained, wherein, in a case where the sheet is conveyed only by the second conveyance unit, a second conveyance amount is obtained, and wherein, in a case where a sheet is conveyed by both the first conveyance unit and the second conveyance unit, cooperative conveyance amount is obtained by subjecting the first conveyance amount and the second conveyance amount to weighted average, where difficulty of slipping of the first or second conveyance unit to the sheet is used as a weighting coefficient in the weighted average, wherein, based on the cooperative conveyance amount, a remaining conveyance amount is calculated from any two conveyance amounts, wherein the two conveyance amounts are from among (i) the cooperative conveyance amount, (ii) the first conveyance amount, and (iii) the second conveyance amount, and wherein a correction value for conveyance is set from the calculated remaining conveyance amount.
