Abstract
Provided is an image forming apparatus which enables control to change a longitudinal magnification of an image transferred on a sheet in a sheet conveyance direction by changing a rotation speed of a second transfer section while prohibiting misalignment of transfer without requiring a changing time of the longitudinal magnification which causes the decreasing of productivity.
Claims7
An image forming apparatus, comprising:
- an image carrier to carry a toner image;
- a toner image forming section to form the toner image on the image carrier:
- an intermediate transfer member to transfer the toner image:
- a first transfer section to transfer the toner image on the image carrier onto the intermediate transfer member, and
- a second transfer member to conduct secondary transfer in which the toner image transferred by the first transfer section is transferred onto a sheet and convey the sheet,
- wherein the control section controls a magnification of the toner image transferred onto the sheet at a secondary transfer position in a sheet conveyance direction to be a target value by changing a rotation speed of the second transfer section while a rotation speed of the intermediate transfer member remains unchanged so as to change a conveyance speed of the sheet.
