摘要： An image forming apparatus including an image forming device on which toner images are formed; a transfer device for transferring the toner images onto a record medium; a voltage-application unit for applying a transfer voltage to the transfer device; a current-detection unit for detecting current flowing between the image forming device and the transfer device; a storage unit for storing a first current value detected at a non-operation position of the transfer device, and a second current value detected at an operation position of the transfer device; and a transfer device state-determination unit for determining the presence of the transfer device and the occurrence of an anomaly in a contact operation of the transfer device with the image forming device and a shunt operation in which the transfer device is moved away from the image forming device.

摘要： A color electrophotographic apparatus eliminates necessity of mechanism for urging the developer from the front side. The developer is placed away from a photo conductor. On both sides of the developer, mutually cooperated gears are provided. One of the gear meshes with a drive gear with a clutch for driving the developer. The other gear is meshed with a brake gear coupled with a brake mechanism whose brake function can be turned On and OFF by an electric signal. The drive gear is arranged to urge the developer onto the photo conductor by rotation thereof. When the gear of the developer rotates, the brake gear is arranged at a position to urge the developer onto the photo conductor. The torque to start slippage of the brake is set at a value to be greater than a force of a spring pushing back the developer.

摘要： An electrophotographic image forming system having a form cassette for storing forms, a transfer unit for forming an image, a feeder for feeding the forms to the transfer unit and a fusing device for fusing transferred image of the form. The electrophotographic image forming system provides in a path for feeding the form with unfused colored particles (toner) deposited thereon, a form guide so as to contact the non-printing area of the surface of the form with unfused colored particles (toner) deposited thereon.
