Abstract: A fixing device includes a flexible rotating fixing belt, a pressing member, a heating part, a guide member and a contact force changing part. The pressing member forms a pressing area with the fixing belt. The heating part heats the fixing belt from an outside of the fixing belt. The guide member comes into contact with an inner circumferential face of the fixing belt to support the fixing belt so as to face the heating part. The contact force changing part moves the guide member in directions close to or away from the fixing belt to change a contact force between the guide member and the fixing belt depending on a pressure of the pressing area.

Abstract: A fixing device includes a first fixing member, a second fixing member, a charging portion, and a control portion. The first fixing member makes contact with a toner image on a sheet conveyed along a conveying passage. The second fixing member forms a nip. The charging portion generates an application current. The control portion can perform an application mode, in which the application current is generated, and a standby mode, in which no application current is generated. The control portion performs the application mode during a first period after initial start-up until the passage of a predetermined period and performs the standby mode during a second period after the passage of the first period until the passage of a predetermined period.
