Abstract: An electrical connector of an image forming apparatus exposes outward from a bottom surface of the image forming apparatus. An electrical connector of a sheet feeder protrudes from a top surface of the sheet feeder. The sheet feeder has a slider configured to be horizontally movable, while holding the electrical connector of the sheet feeder, between a connecting position at which the electrical connectors of the sheet feeder and image forming apparatus are connected and a disconnecting position at which the electrical connectors are disconnected. A locking member having a locking engaged part is fixed to the image forming apparatus. When the slider is moved to the connecting position, a locking engaging part of the slider engages the locking engaged part of the locking member so that the locking member and the slider are locked such that they cannot be separated vertically from each other.

Abstract: A transfer unit includes first and second rollers of which the second has an elastic layer larger in the axial direction than the first, a roller holder, and a switching cam. One of the first and second rollers is, by rotating the roller holder, arranged opposite the image carrying member and, by rotating the switching cam, arranged selectively either at a reference position to form a transfer nip or at a released position to lie away from the image carrying member. Let the length of the elastic layer of the first roller in the axial direction, the width of the effective image area on the image carrying member to which the toner image can be transferred, and the width of the recording medium of the maximum size allowing transfer using the first roller be L1, L3, and L4 respectively, L4

Abstract: An image forming apparatus includes a rail member and an intermediate transferring device. The rail member mounted to a frame. The intermediate transferring device attachably/detachably mounted to the rail member. The intermediate transferring device includes a toner carrier, a cleaning member, a first transmission mechanism and a second transmission mechanism. The toner carrier is driven to be rotated by a driving source, and configured to carry a toner image. The cleaning member is driven to be rotated by the driving source, and configured to remove a toner which remains on the toner image carrier. The first transmission mechanism configured to transmit a driving force of the driving source to the toner image carrier. The second transmission mechanism configured to transmit the driving force of the driving source to the cleaning member. The first transmission mechanism and the second transmission mechanism are arranged between the frame and the rail member.

Abstract: An image forming apparatus includes an image forming portion, an image input portion, a transfer unit, a transfer voltage power supply, and a control portion. The transfer unit includes a transfer roller having a metal shaft and an elastic layer laid around the outer circumferential face of the metal shaft to form a transfer nip by keeping the elastic layer in pressed contact with an image carrying member, and transfers a toner image formed on the image carrying member to a recording medium as it passes through the transfer nip. The transfer unit includes, as the transfer roller, a first roller, and a second roller having a larger axial-size elastic layer compared to the first roller. The control portion arranges first or second roller opposite the image carrying member according to width-direction sizes of the recording medium and the image data fed to the image input portion.

Abstract: An image forming device includes: a secondary transfer roller configured to secondarily transfer a toner image transferred to an intermediate transfer belt, to a transfer paper; separating plates; and a power supply circuit configured to apply bias voltages to the separating plates. The separating plates are configured to separate the transfer paper from the intermediate transfer belt when the bias voltages are applied to the separating plates. The separating plates include two or more separating plates installed along a direction perpendicular to the transfer paper conveying direction. The bias voltages are applied to the separating plates independently of each other depending on a toner amount distribution of the toner image transferred to the transfer paper, in the direction perpendicular to the transfer paper conveying direction.
