Abstract:
1. An image forming apparatus that forms an image on a sheet fed by a feeding roller from a sheet cassette mounted on an apparatus main body, the image forming apparatus comprising: a drive portion that is provided in the apparatus main body to drive the feeding roller; a drive transmission portion that is capable of changing between a first state in which the driving of the drive portion is transmitted to the feeding roller to feed the sheet by the feeding roller and a second state in which the driving of the drive portion is not transmitted to the feeding roller; a switching portion that switches the drive transmission portion from the second state to the first state to make the feeding roller feed the sheet, and that returns the drive transmission portion, from the first state to the second state and stays in the second state; and a controller that drives the drive portion for a time necessary to return the drive transmission portion from the first state to the second state so as to make the drive transmission portion be in the second state when the apparatus main body is initially installed and a power of the apparatus main body is turned on.
