Image forming apparatus with rotating guide member that guides sheet

An image forming apparatus comprising:

• a first conveying member that conveys a sheet on which an image is formed;
• a guide member rotatable between a first guiding position where the guide member guides a sheet that is conveyed by the first conveying member toward a first direction and a second guiding position where the guide member guides the sheet toward a second direction that is different from the first direction;
• a second conveying member that conveys a sheet that has been guided toward the first direction by the guide member;
• a third conveying member that conveys a sheet that has been guided toward the second direction by the guide member;
• a driver that drives the guide member so that the guide member rotates;
• an acquiring portion configured to acquire a basis weight of a sheet;
• and
• a controller configured to control the driver so as to change a rotation speed of the guide member which contacts the sheet, based on the basis weight acquired by the acquiring portion.
