Abstract:
1. An image forming apparatus comprising: a light emitting portion emitting light; an optical scanning portion scanning a display surface with the light emitted from the light emitting portion; a changing portion rotating an image formed on the display surface through the scanning with the light by using a position near the center as a rotation axis to change an orientation of the image; a drawing position changing portion changing a position of the image; a sensing portion sensing whether or not a human is present within a sensing region set near the display surface and sensing a moving state of the human when the human is present within the sensing region; and a control portion controlling driving of the drawing position changing portion based on a sensing result of the sensing portion, wherein the changing portion changes the orientation of the image based on an activation state of the drawing position changing portion, and when the human is moving within the sensing region, the control portion controls the driving of the drawing position changing portion such that the position of the image is changed to remain located forward of the moving direction of the human.
