摘要： An image forming apparatus includes a sheet transport channel including a registration roller for supplying a sheet that is fed from a tray to an image recording section at predetermined timing. A brake forcibly stops rotation of the registration roller. A sensor senses the occurrence of an abnormality in the paper transport channel during transport of the sheet. A controller activates the brake when the sensor has detected the abnormality. Therefore, when a POP jam occurs, sheet rushing into the cleaner due to an overrun can be reliably prevented. Also, in the case of feeding a sheet to prevent a guillotine jam, sheet rushing into the image recording section due to idle rotation of the registration roller can be prevented reliably.

摘要： An image forming apparatus includes an image carrying body on which a toner image is created. A sheet carrying/transporting rotational body adsorbs a recording sheet to which the toner image on the image carrying body is transferred, and transports the sheet. The recording sheet is detached after transfer from the sheet carrying/transporting rotating body, and an assisting device thrusts against the non-image area of the recording sheet to limit its detachment from the sheet carrying/transporting rotating body. The image forming device can prevent transportation failure and image smudging that is otherwise generated when a thick sheet provided with a curl before it is adsorbed to a sheet carrying/transporting rotational body is detached in the curved state from the rotational body and transported to a fusing means.

摘要： A rear end plate having openings is bonded to a rear end portion of a transfer film through urethane sponge. To attach the rear end portion of the transfer film to a coupling member of a frame of a transfer material carrying body, restricting portions of respective restricting members are fixed to the coupling member through the respective openings of the rear end plate. The restricting portions of the restricting members abut the top face of the rear end plate so as to restrict a radial movement of the rear end plate and allow its circumferential movement.

摘要： A predetermined sheet retaining plane C for absorbing a record sheet is provided in the circumferential surface of a sheet carrier, and a low-reflectivity area which is to be partially covered with the record sheet is provided at a leading portion of the sheet retaining plane C. Reflection photosensors for detecting the reflectivity of the sheet carrier including the low-reflectivity area are disposed around the sheet carrier. Whether a record sheet is held in the sheet retaining plane C is judged on the basis of detection signals of the photosensors.

摘要： An image forming apparatus capable of preventing a transfer material detecting unit from making any detection error when the surface of a transfer drum becomes opaque, and restraining transfer film replacement intervals from being shortened with a simple constitution. The image forming apparatus is provided with a transfer material detecting unit for detecting conditions in which a transfer material is conveyed on a transfer material carrier, and a transfer material peeling unit for peeling the transfer material off the transfer material carrier by contacting the surface of the transfer material carrier. At least part of the transfer material peeling unit is disposed so that it at least linearly contacts the axial surface of the transfer material carrier at the same position as that of the transfer material detecting unit in the axial direction of the transfer material carrier.
