Abstract

A sheet conveyance device includes a shape detecting portion, and a switch control portion. The shape detecting portion detects a shape of a sheet at a detection position between a first conveyance member and a second conveyance member. The switch control portion, when a front end of the sheet has passed a arrangement position at which the first conveyance member is arranged, switches an detection interval at which the shape of the sheet is detected by the shape detecting portion, to a first interval that corresponds to a rotation speed of the first conveyance member, and when a rear end of the sheet has passed the arrangement position, switches the detection interval to a second interval that corresponds to the rotation speed of the second conveyance member.
