摘要： A cleaning device includes a web sheet, a holding member, a reel member, a drive device, a pressing member, and a rotational load-applying device. The web sheet slides against and cleans a surface of a cleaning target object. The holding member holds the web sheet wound around the holding member to be reeled out. The reel member has the web sheet wound around the reel member to be reeled in. The drive device drives the reel member to rotate. The pressing member presses the web sheet against the cleaning target object. The rotational load-applying device applies a load to rotation of the holding member. The load is changeable depending on an amount of the web sheet held by the holding member.

摘要： A fixing device includes a separator disposed downstream from a nip former in a recording medium conveyance direction and isolated from a pressure rotator via a fixing belt. The separator stretches the fixing belt. A presser is interposed between a fixing nip formed between the living belt and the pressure rotator and an upstream end of the separator in a rotation direction of the fixing belt. The presser comes into contact with an inner circumferential surface of the fixing belt to press the fixing belt against the pressure rotator. A pressure adjuster, contacting the pressure rotator, changes a pressing position of the pressure rotator relative to the fixing belt to adjust pressure exerted from the pressure rotator to the fixing belt. A presser position adjuster, contacting the presser, changes a presser position of the presser relative to the fixing belt according to the pressing position of the pressure rotator.
