摘要： An image forming machine equipped with a transfer belt unit includes a safety detecting means for detecting the completion of setting of an opening/closing member constituting the image forming machine, and a controlling means for controlling the operation of a driving means for a driving roller on the basis of a signal from the safety detecting means. When the safety detecting means signals the completion of the setting after signaling the incompletion of the setting, the controlling means controls the driving means so as to perform a reverse driving, thereby driving the driving roller reversely by a predetermined amount.

摘要： A transfer plate which also serves as a sheet guide plate is pushed by a torsion spring. A minimum gap less than 0.2 mm between a guide surface of the transfer plate and the surface of a photoreceptor drum is maintained to be smaller than the thickness of a transfer sheet by a spacer member provided on the guide surface. When the sheet passes through the gap between the drum surface and the guide surface, the transfer plate is pushed down by the sheet and the sheet is pressed onto a toner image formed on the drum surface with an appropriate pressure by the pushing force of the torsion spring. At this time, a transfer voltage is applied to the transfer plate, so that the toner image on the drum surface is transferred to the sheet.

摘要： A cleaning device for cleaning an endless transfer belt which is made of elastic material and stretched between a first roller and a second roller, one of the two rollers being adapted for driving the belt, the transfer belt being able to come into contact with a copy sheet on one stretch side of the transfer belt to convey the copy sheet in a direction from the first roller to the second roller. The cleaning device is provided with a cleaning blade member for removing toner from the belt. The cleaning blade member is disposed on the other stretch side of the transfer belt and near the second roller, being pressed perpendicularly against an outside surface of the belt, and having a leading end portion which is flexed and capable of coming into a line contact with the belt over an entire width of the belt when the belt is driven. The amount of pressing force of the blade against the belt will be adjusted depending on the sensed temperature of the belt.

摘要： A sheet conveyance guide is configured of separation claws for separating the paper from a conveyer and transfer belt and a movable sheet guide for guiding the paper to a fixer entrance sheet guide. The separation claws are arranged on the upstream side of the movable sheet guide. The movable sheet guide is rotatable about a pivot shaft with its distal end abutted by gravity upon the upstream end part of the fixer entrance sheet guide.The separation claws and movable sheet guide are axially supported so as to rotate on pivots.The sheet conveyance guide moves together with the vertical movement of the conveyer and transfer belt while the abutment point of the separation claws upon the conveyer and transfer belt moves to the appropriate position.
