The intermediate transferring device attachably/detachably mounted to the rail member. The intermediate transferring device includes a toner carrier, a cleaning member, a first transmission mechanism and a second transmission mechanism. The toner carrier is driven to be rotated by a driving source, and configured to carry a toner image. The cleaning member is driven to be rotated by the driving source, and configured to remove a toner which remains on the toner image carrier. The first transmission mechanism configured to transmit a driving force of the driving source to the toner image carrier. The second transmission mechanism configured to transmit the driving force of the driving source to the cleaning member. The first transmission mechanism and the second transmission mechanism are arranged between the frame and the rail member.

Abstract: An image forming apparatus includes a discharge guide provided downstream of a fixing device in a sheet transport direction, and configured to guide a sheet on which a toner image has been fixed, to a sheet discharge port formed in a main body of the image forming apparatus, the discharge guide including an air vent for cooling the sheet, and a cooling fan that blows air to the sheet passing the discharge guide, through the air vent. A fixing device housing includes an air inlet that allows an airflow generated by the cooling fan toward the sheet and reflected thereby, to be introduced into inside the fixing device housing.

Abstract: A fixing device includes a temperature detection unit that detects temperature associated with temperature of an abutting section of a fixing roller and a pressing roller, and a control unit that controls a driving motor based on detection temperature by the temperature detection unit. When the fixing device is activated, if it is determined that detection temperature by the temperature detection unit is not equal to or less than predetermined temperature, the control unit drives the driving motor at a setting speed set in advance, and if it is determined that the detection temperature is equal to or less than the predetermined temperature K, the control unit drives the driving motor at a predetermined low speed lower than the setting speed.

Abstract: An image forming apparatus includes a fixing device, a discharge roller pair, a detection portion, and a discharge control unit. The discharge roller pair discharges a sheet on which a toner image has been fixed in the fixing device to a discharge tray via a discharge port. The detection portion detects a rear end of the sheet being conveyed from the fixing device toward the discharge port. The discharge control unit performs control so that, within a prescribed period from a point in time of detection of the rear end of the sheet by the detection portion to when the rear end of the sheet passes through the discharge roller pair, a discharge speed of the sheet is reduced to a value lower than a reference speed, and after a lapse of the prescribed period, the discharge speed is increased back to the reference speed.

Abstract: An image forming apparatus includes a housing frame, a scanner frame, a first support frame, a second support frame, and a connecting member. The second support frame supports the scanner frame. The second support frame includes a horizontal support member and a vertical support member. The scanner frame includes a member to be connected. The insertion plate of the connecting member penetrates through the opening of the member to be connected in the first direction, and is inserted through the opening of the vertical support member. The insertion plate has an upper face located in contact with an upper end face of the opening of the member to be connected, at least via one position, and has a lower face located in contact with a lower end face of the opening of the vertical support member, at least via two positions spaced from each other in the second direction.

Abstract: A fixing device includes a fixing member, a pressuring member, a separating claw separating a recording medium from the fixing member and a moving mechanism of the separating claw. The moving mechanism includes a biasing member, coaxial two input gears having different numbers of teeth, a bearing depression and a shaft protrusion. The two input gears rotate according to rotation the fixing or pressuring member while shifting by a difference of the numbers of teeth for each rotation. The bearing depression is depressed in one input gear, and has an inclined contact face. The shaft protrusion is protruded from the other input gear, and has an inclined distal end face contact with the contact face. The two input gears rotate to repeat coincidence of inclination directions of the contact face and the distal end face and shifting the inclination directions, and reciprocatingly move the separating claw.
