摘要： An image forming apparatus includes a contact transfer device, a bias applying device, a transfer current sensor, a leakage current adjustor, and a controller. The contact transfer device is configured to transfer a toner image onto a surface of a sheet conveyed in a predetermined direction. The bias applying device is configured to apply a bias to the contact transfer device. The transfer current sensor is configured to sense a value of a transfer current flowing through the sheet at an image transfer position. The leakage current adjustor is configured to adjust an amount of a leakage current flowing from the contact transfer device along the surface of the sheet. The controller is configured to control the leakage current adjustor to maintain an amount of the transfer current within a reference range based on the value of the transfer current sensed by the transfer current sensor.

摘要： An image forming apparatus having an image carrier that carries a toner image; an opposed member that is provided so as to be opposed to the image carrier; an application device that applies a bias to the opposed member; and a control device that controls the application device to apply a first bias and thereafter a second bias to the opposed member so as to remove toner from the opposed member. The first bias has an absolute value that is large enough to cause discharge from the opposed member into air. The second bias has an absolute value that is too small to cause discharge from the opposed member into the air, and has a reverse polarity to the first bias.

摘要： When a number of print pages, a driving time or a toner adhering amount exceeds a cleaning trigger value during no transfer operation, a circumferential speed of a secondary transfer roller is changed with respect to a circumferential speed of an intermediate transfer belt so as to clean the secondary transfer roller. Particularly, a surface of the secondary transfer roller is totally cleaned when the circumferential speed of the secondary transfer roller is made relatively faster and then slower or vice versa than the circumferential speed of the intermediate transfer belt because the surface of the secondary transfer roller is elastically deformed in both upstream and downstream directions so that the residual toner on the uneven foam surface of the secondary transfer roller is extruded.

摘要： A first roll brush is formed from material having the positive triboelectric charge polarity against toner. A positive bias is applied to the first roll brush through a first collection roller by a first bias application device. A second roll brush is formed from material having the negative triboelectric charge polarity against toner. A negative bias is applied to the second roll brush through a second collection roller by a second bias application device. Thus, the first and second roll brushes are applied by each of biases having polarity identical to the triboelectric charge polarity of material of the roll brush against toner. This enhances cleaning performance of both the roll brushes and prevents degradation of the cleaning performance.
摘要翻译：第一辊刷由具有对调色剂的正摩擦带电极性的材料形成。通过第一偏压施加装置通过第一收集辊将正偏压施加到第一辊刷上。第二辊刷由对调色剂具有负摩擦带电极性的材料形成。通过第二偏压施加装置通过第二收集辊将负偏压施加到第二辊刷。因此，第一和第二辊刷通过具有与辊刷材料的摩擦带电极性相反的极性的各偏压施加到调色剂上。这提高了两个辊刷的清洁性能，并防止了清洗性能的降低。

摘要： A secondary cleaning device has a cleaning brush, collection roller, and controller. The cleaning brush is driven by a drive mechanism and thereby rotates in a state that brush fibers thereof are contacting with a secondary transfer belt to collect toner on the secondary transfer belt. The collection roller is driven by another drive mechanism and thereby rotates in a state contacting with the cleaning brush to collect toner from the cleaning brush. The collection roller rotates in such a manner that the collection roller and the cleaning brush move in the same direction with each other at a contact area between the collection roller and the cleaning brush. The controller controls the drive mechanism such that the circumferential speed ratio of the collection roller with respect to the cleaning brush is greater than one and smaller than two.
