Abstract
An image forming apparatus includes an image bearing member, a transfer member, a conveyance unit arranged upstream of a transfer portion in a sheet conveyance direction, an upstream conveyance unit arranged upstream of the conveyance unit, a drive unit configured to drive the conveyance unit; and a controller to control the drive unit to change a conveyance speed of the conveyance unit. In a case where a trailing edge of the sheet passes through the upstream conveyance unit after a leading edge of the sheet in the sheet conveyance direction has entered the transfer portion, the conveyance unit conveys the sheet by a first speed before the trailing edge of the sheet passes through the upstream conveyance unit, and by a second speed that is faster than the first speed after the trailing edge of the sheet has passed through the upstream conveyance unit.
