Abstract
An image forming apparatus includes an endless belt that is stretched around plural rollers; a driving unit that drives the belt to rotate; a contact member that is in contact with a part of a surface of the belt, the part being supported by one of the plural rollers; and a switching device that changes an image forming mode by displacing at least one of the plural rollers. When the image forming mode is changed by the switching device, the belt is rotated by the driving unit in a normal direction at a speed higher than a speed of reverse rotation of the roller that is in contact with the contact member with the belt interposed therebetween.
Claims6
An image forming apparatus comprising:
- an endless belt that is stretched around a plurality of rollers;
- a driving unit that drives the belt to rotate;
- a contact member that is in contact with a surface of the belt at a location where the surface is supported by a first roller of the plurality of rollers;
- and
- a switching device that changes an image forming mode by displacing at least one of the plurality of rollers,
- wherein, when the image forming mode is changed by the switching device, the belt is rotated by the driving unit in a normal direction at a speed higher than or equal to a speed of reverse rotation of the first roller that is in contact with the contact member with the belt interposed therebetween.
