Abstract: An image forming apparatus includes a plurality of image forming portions, an intermediate transfer belt, a belt displacement detector, an attraction force changer, and a controller. The intermediate transfer belt is an endless belt wound around drive and driven rollers. The belt displacement detector detects displacement of the intermediate transfer belt in a rotation axis direction of the driven roller. The attraction force changer is operable to change electrostatic attraction force of the driven roller with respect to the intermediate transfer belt exerted on each of opposite end sides of the driven roller in the rotation axis direction thereof. When the belt displacement detector detects displacement of the intermediate transfer belt, the controller makes the attraction force changer increase the electrostatic attraction force of the driven roller with respect to the intermediate transfer belt exerted on a side opposite to a side toward which the displacement has taken place.

Abstract: An image forming apparatus (1) includes image bearing members (31), transfer members (52), and a power supply section (57). The image bearing members (31) each bear one of toner images in different colors from one another. The transfer members (52) are located opposite to the image bearing members (31). The power supply section (57) charges the transfer members (52). Through the above, the toner images on the respective image bearing members (31) are transferred to a moving transfer target (51).

Abstract: A cleaning device includes a housing, a cleaning blade, and first and second sealing members. The housing has formed therein an opening facing an image carrying member. The cleaning blade removes toner that remains attached to the image carrying member while being in contact with the circumferential surface of the image carrying member. The first and second sealing members prevent waste toner inside the housing from leaking out through a gap between the housing and the image carrying member, owing to the first and second sealing members abutting on the circumferential surface of the image carrying member.

Abstract: An image forming apparatus includes an image bearing member, a charger, a light exposure device, and a development device. The charger charges a circumferential surface of the image bearing member to a positive polarity. The light exposure device exposes the charged circumferential surface of the image bearing member to light to form an electrostatic latent image on the circumferential surface of the image bearing member. The development device supplies a toner to the electrostatic latent image through application of a developing bias. The developing bias is a voltage of an alternating current voltage superimposed on a direct current voltage. The alternating current voltage has a frequency of 4 kHz or higher and 10 kHz or lower. The image bearing member includes a conductive substrate and a photosensitive layer of a single layer. The image bearing member satisfies formula (1) 0.60 ≦ V ( Q / S ) × ( d / ɛ r · ɛ 0 ) ( 1 )
