  • Patent number: 10831132
    Abstract: A transfer device includes an intermediate transfer belt configured to bear a toner image and rotate, a transferor configured to contact the intermediate transfer belt via a recording medium and form a transfer nip, a guide configured to guide the recording medium conveyed to the transfer nip, and a pressure reducing device. The intermediate transfer belt is shaped as an endless belt. The pressure reducing device is configured to reduce pressure-contact force of the transferor against the intermediate transfer belt as the recording medium advances in the transfer nip. Therefore, a trailing end of the recording medium does not move toward the intermediate transfer belt when the trailing end of the recording medium has passed the guide.

A first toner pattern image is formed on the image bearer, transferred onto the transfer rotator, and passed past the blade at least twice together with rotation of the transfer rotator in at start-up of the image forming apparatus. A second toner pattern image is formed on the image bearer after the start-up and during passage of a non-image area in which toner images are not formed. A range of the first toner pattern image is wider than a range of the second toner pattern image in a width direction perpendicular to a direction of travel of the image bearer.

  • Patent number: 10185255
    Abstract: An image forming apparatus includes an image bearer to bear a toner image, a nip forming member contacting the image bearer to form a transfer nip, and a transfer power source. The transfer bias has a transfer peak value to electrostatically move toner from the image bearer to the recording sheet and an opposite-peak value to electrostatically move less toner from the image bearer to the recording sheet than the transfer peak value. An opposite-peak duty of the transfer bias is less than 50%. The opposite-peak duty is tr/T×100% where T is one cycle of the transfer bias and tr is a time period during which the transfer bias is on a side of the opposite-peak value relative to an offset voltage of the transfer bias in the one cycle T.

  • Patent number: 10114331
    Abstract: A transfer device includes an image bearer, a rotatable body, a solid lubricant assembly, and a guide. An image bearer bears an image. The rotatable body forms a transfer nip with the image bearer to rotate in contact with a recording medium. An image on the image bearer is transferred onto the recording medium at the transfer nip. The solid lubricant assembly includes a solid lubricant and extends in a longitudinal direction of the rotatable body. The solid lubricant assembly applies a solid lubricant to at least one of the rotatable body and the image bearer. The guide guides the recording medium and positions the solid lubricant assembly.
