摘要： The present invention provides a fixing device that may include a nip member, a rotating body and an endless belt. The endless belt may be in sliding contact with the nip member. The rotating body may constitute a nip region. The nip region may define a first, second and third imaginary planes. The first imaginary plane may be perpendicular to the sliding direction. The second imaginary plane may be perpendicular to the axial direction of the rotating body and may contain a first end portion of the nip region. The third imaginary plane may contain a second end portion of the nip region. The first surface may be a convex shape in a first cross-section along the first imaginary plane, and may be concave shape concaved in a direction opposite to the rotating body in second and third cross-sections along the second and third imaginary planes.

摘要： A fixing device may include a metal plate, an endless belt, a rotating body, and a stay. The metal plate may have a main part comprising a first end portion, a second end portion, and a center portion positioned therebetween and having rigidity higher than that of the first end portion and the second end portion. The endless belt may have an inner peripheral surface configured to be in sliding contact with the metal plate. The main part may be aligned with the rotating body in a direction from the metal plate to the rotating body. The stay may be disposed opposite to the nip region with respect to the metal plate. The stay and the main part of the metal plate may be deformable upon application of the load to the stay such that the main part may provide a convex shape protruding toward the rotating body.

摘要： A developer supply device is provided, which includes a transfer board including an activating section and an always-transferring section. The activating section is disposed in a position close to a developer holding member and lower than a position where development agent is transferred onto the developer holding member. The activating section is supplied with an activating voltage for making the development agent leave a developer transfer path and drop into the developer storage section during an activating process performed at an initial stage of a developer transferring operation while supplied with the transfer bias voltage after the activating process. The always-transferring section is disposed across a position facing the developer storage section to a position lower than and adjacent to the activating section, and always supplied with a transfer bias voltage during the developer transferring operation.

摘要： A fixing device configured to thermally fix a developing agent image to a recording sheet includes a fixing belt having a tubular shape defining an inner space, a heat generating member and a nip plate which are disposed in the inner space, and a rotating member disposed outside the inner space. The nip plate includes a plate-shaped portion holding the fixing belt against the rotating member, and a bent portion located downstream of the plate-shaped portion in a conveying direction of the recording sheet and bent to define a recess facing away from the rotating member. The bent portion protrudes farther away from the heat generating member than the plate-shaped portion. A temperature sensor for sensing a temperature of the nip plate is fitted in the recess of the bent portion so as not to be displaced in the conveying direction.
