In a front/back reversing unit, a base metal sheet having rollers attached thereon is engaged with a rotation spindle fixed to a fitting such that the base metal sheet is rotatable in a horizontal direction. When an operation of rolling up a print target medium is started and if winding tension with respect to the print target medium to be wrapped around a winding shaft becomes unbalanced, the front/back reversing unit rotates in accordance with the winding tension so as to balance the winding tension. Then, when the winding tension applied to the print target medium becomes balanced, the front/back reversing unit is returned to its original position by an elastic member, and the roller of the front/back reversing unit and the winding shaft become substantially parallel to each other.

Image forming apparatus and winding-deviation prevention method

A static charge eliminator includes an abutment member which abuts on a print target medium so as to eliminate static charge on a lower flow side than a position where the print target medium separates from and comes in contact with a predetermined roller on a conveyance path of the print target medium, and a supporting member which supports the abutment member such that the abutment member rotates around a rotation axis of the roller, in which the supporting member rotates while following a change in a pressing force from the print target medium via the abutment member which occurs when a winding angle using the position where the print target medium separates from and comes in contact with the roller as a reference point is changed in accordance with a winding amount of the print target medium.

Static charge eliminator and image forming system

A printing device includes a first ejector that ejects a recording medium to an exterior, a second ejector that enhances a rigidity of the recording medium more than by the first ejector, and ejects the recording medium to the exterior, and an ejector selector that selects either the first ejector or the second ejector.

Printing device

A printing apparatus prints an image on a recording medium unwound by an unwinder. The recording medium is wound around a first winding shaft in order from a beginning edge to an ending edge of the recording medium. The wound recording medium is rewound, and the rewound recording medium is wound around a second winding shaft in order from the ending edge to the beginning edge of the recording medium.

A roll sheet image forming apparatus includes an introduction opening and a guide plate. Instead of a continuous sheet held in an apparatus main body, a continuous sheet for option feeding provided at an outside is introduced into the apparatus main body through the introduction opening. The guide plate is for splicing a lead sheet and a continuous sheet. When feeding the continuous sheet, a feeding unit is pulled out from the apparatus main body, a lead sheet is set to be conveyable towards an image forming unit, the feeding unit is again accommodated in the apparatus main body, a front end of the continuous sheet is placed on the guide plate, a rear end of the lead sheet is placed on the guide plate through the introduction opening, the rear end and the front end are spliced by a bonding member and then the feeding unit operates.

Roll sheet image forming apparatus

A printing apparatus includes a controller that, upon receipt of a printing suspension instruction during printing on a print medium by a printing device, causes a conveyor to stop a conveyance of the print medium from an upstream side to a downstream side after printing a mark on the print medium, causes the conveyor to convey the print medium from the downstream side to the upstream side, then to stop the conveyance of the print medium after a sensor detects the mark printed on the print medium, and upon receipt of a printing restart instruction, causes the conveyor to convey the print medium from a returned position where the print medium is stopped to the downstream side and controls a timing of a printing based on a detection of the mark by the sensor.

Printing apparatus, printing method, and storage medium which control printing based on detection of a mark by a sensor

In an image forming apparatus provided with a detachable fixing unit having fixing paired-rollers, a heating unit heats at least one of the fixing paired-rollers, and a temperature detecting unit detects a temperature of the detachable fixing unit. The image forming apparatus is further provided with an adjustment mechanism for preventing the detachable fixing unit from being taken out from the apparatus body, when the temperature detecting unit determines that the temperature of the detachable fixing unit exceeds a predetermined value, and allowing the detachable fixing unit to be taken out from the apparatus body, when the temperature detecting unit determines that the temperature of the detachable fixing unit is the predetermined value or less, whereby protecting users from getting their hands burned when taking out the detachable fixing unit from the apparatus body.

Image forming apparatus

An upper body which can be shifted from and toward a lower body through a link mechanism is formed. A drum unit and a toner unit are arranged on the side of the upper body. The upper body is opened in the parallel with respect to the lower body with a predetermined interval, by the link mechanism including arms. In the state where the upper body is opened, the drum unit and the toner unit can be detached from and attached to the printer device in frontward and backward directions, by sliding a sliding member arranged on the upper body.

Printer device

A motor starts its rotation, and a clutch is operated to drive both of a first driving force transmission system for color printing, including drum gears, and a second driving force transmission system for monochrome printing, including a drum gear. The clutch is disengaged to stop the first system when a first sensor detects a mark on one photosensitive drum of the first system at the same time that a second sensor detects a mark on one drum driving gear of the first system. Next, when a third sensor detects a mark on another photosensitive drum of the second system at the same time that a fourth sensor detects a mark on another drum driving gear of the second system, the clutch is reengaged. Consequently, positionings of all the photosensitive body drums (drum gears) for color printing to the photosensitive drum (drum gear) for monochrome printing are performed without causing positional differences by inertia at the time of stop.

Image forming apparatus and image forming unit with an improved phase

An image forming apparatus includes a plurality of image carriers arranged side by side along the outer surface of a conveying portion of a transfer belt. The transfer belt is stretched between a first upstream roller and a second downstream roller. An image forming medium is conveyed on the belt so as to have multiple color images transferred thereto. The transfer belt has a swing lever so as to move the belt between a horizontal full color position and an inclined monochrome position. A stationary support roller which is arranged within the transfer belt and at a position nearer to the second downstream roller maintains a position of the image forming medium constant even when a monochrome image is being transferred. In addition, an electrostatic attraction roller located outside the transfer belt is arranged at a specific angle relative to the first roller to assist in the attraction of the image forming medium to the transfer belt.
