摘要： An image forming apparatus including an image bearer, a transfer-bias power source, an environment sensor, and a controller. The controller controls the transfer-bias power source to change the DC component and the AC component, according to the at least one of temperature and humidity detected by the environment sensor and a duty of the transfer bias. The duty is A/(A+B)×100[%] where A denotes an area on a return-directional side to move toner from the recording sheet back to the image bearer, relative to a center value (Voff) of a maximum value and a minimum value of the transfer bias in one cycle of a waveform of the transfer bias, and B denotes an area on a transfer-directional side to move the toner from the image bearer to the recording sheet, relative to the center value (Voff) in the one cycle.

摘要： An image forming apparatus includes an image bearer, a transfer device, and a transfer bias power source. The transfer bias power source is configured to output an alternately switching voltage that alternates between a transfer-directional voltage having a polarity to transfer the toner image from the image bearer onto the recording medium and a return-directional voltage having an opposite polarity to the polarity of the transfer-directional voltage. The transfer bias power source is configured to reduce a target value of Vdc as an image area ratio of a toner image to be printed increases, and to increase the target value of Vdc as the image area ratio reduces, where Vdc is an average value of the alternately switching voltage during printing.

摘要： An image forming apparatus includes an image bearer, a toner image forming device, a nip forming device, a power source, a controller, and a temperature-and-humidity detector. The toner image forming device forms a toner image on the image bearer. The nip forming device contacts the image bearer to form a transfer nip. The power source outputs a transfer bias, in which an alternating current component is superimposed on a direct current component, to transfer the toner image onto a recording medium interposed in the transfer nip. The temperature-and-humidity detector detects a temperature and humidity. The controller controls the power source to output the transfer bias including the direct current component with a smaller absolute value as at least one of the detected temperature and humidity increases.

摘要： A transfer device includes a transfer member and a bias applicator. The transfer member contacts a surface, on which a toner image is borne, of an image bearing body, to form a transfer nip. The bias applicator applies a DC voltage and an AC voltage as transfer bias to transfer the toner image on the image bearing body to a recording sheet in the transfer nip. The bias applicator applies a DC voltage having a same polarity as the DC voltage of the transfer bias and an AC voltage having an amplitude smaller than the AC voltage of the transfer bias or applies the DC voltage having the same polarity as the DC voltage of the transfer bias without applying an AC voltage, when an inter-sheet area that exists on the image bearing body passes through the transfer nip during a continuous image formation period.

摘要： A transfer device includes a transfer bias power source, a switching device, and a sheet dependent condition setting device. The transfer bias power source applies to a transfer member, based on sheet dependent conditions for a recording medium onto which a toner image is transferred, one of a DC transfer bias and a superimposed transfer bias including an alternating current (AC) component superimposed on a DC component. The switching device switches a transfer mode between a DC transfer mode in which the DC transfer bias is applied to the transfer device and a superimposed-bias transfer mode in which the superimposed transfer bias is applied to the transfer device. The sheet dependent condition setting device sets arbitrarily at least one of the sheet dependent conditions for the recording medium at the superimposed-bias transfer mode. The sheet dependent conditions include a DC component value and an AC component value.

The thin film transistor (T2) has a gate terminal connected to a first node (N1), a drain terminal connected to the input terminal (43), and a source terminal connected to the output terminal (51). The thin film transistor (TA) has a gate terminal connected to the input terminal (48), a drain terminal connected to the first node (N1), and a source terminal connected to the input terminal (49). The potential of the control signal (CT) becomes the high level in a control period as a period except for the first one horizontal scanning period in a vertical blanking period. The level down signal (LD) is a potential lower than DC power supply potential (Vss).

摘要： An image forming apparatus includes a nip forming member and a transfer bias output device that outputs a transfer bias to form a transfer electric field in a transfer nip between the nip forming member and an intermediate transfer member. Upon transfer of a composite toner image including a particular toner image onto a recording medium in the transfer nip, the transfer bias output device outputs the transfer bias including a first superimposed bias in which a direct current (DC) component is superimposed on an alternating current (AC) component. Upon transfer of the composite toner image without the particular toner image onto the recording medium in the transfer nip, the transfer bias output device outputs one of the transfer bias including a second superimposed bias having a peak-to-peak value of the AC component smaller than that of the first superimposed bias and the transfer bias including only the DC component.
