A transfer device includes: a transfer drum that has a groove-like recess extending in an axial direction in an outer circumferential portion thereof, rotates about an axis thereof, and comes into contact with a medium being transported at a portion thereof on an upstream side of the recess in a rotation direction; a nip member, the nip member and the transfer drum forming therebetween a nip part where the medium is nipped; an application member that applies a voltage to the nip part where the medium is nipped, so that an image is transferred to the medium; and a contact mechanism that causes the nip member to come into contact only with a portion on the upstream side of the recess in the transfer drum in the rotation direction at a transfer-start time when the transfer of the image to the medium starts.

A sheet transportation device includes a first transport roller that transports a sheet member toward a first direction, a second transport roller that is arranged on a downstream side of the first transport roller in a transport direction of the sheet member and transports the sheet member in a second direction different from the first direction, and a guide portion that guides the sheet member by coming into contact with a leading end of the sheet member in a region on a second transport roller side with respect to a first line extending from a part of the first transport roller, in which the sheet member is pinched, in the first direction and on an opposite side to a first transport roller side with respect to a second line extending from a part of the second transport roller, in which the sheet member is pinched, in the second direction.

A sheet conveyance apparatus includes a first conveyance portion configured to convey a sheet, a second conveyance portion configured to convey the sheet, the second conveyance portion including an abutment portion configured to form a loop on the sheet by being abutted against a leading edge of a sheet conveyed by the first conveyance portion, a curved guide portion, which is curved, configured to guide the sheet conveyed by the first conveyance portion to the second conveyance portion, and a rotary member arranged downstream of the first conveyance portion and upstream of the second conveyance portion in a sheet conveyance direction, and configured to be driven to rotate by a surface of the sheet that is guided by the curved guide portion, the surface sliding against the curved guide portion.

A flexible touch panel including a flexible substrate bent in a first direction, and a touch sensor unit disposed on the flexible substrate, the touch sensor unit including a bridge extending in a second direction intersecting the first direction.

A developing cartridge includes: a casing; a developing roller rotatable about a developing axis extending in a first direction and positioned at one end portion of the casing in a second direction crossing the first direction; a developing electrode electrically connected to the developing roller and positioned at one end portion of the casing in the first direction; a supply roller rotatable about a supply axis extending in the first direction and configured to supply toner to the developing roller; a supply electrode electrically connected to the supply roller and positioned at one end portion of the casing in the first direction; and an IC chip having an electrical contact surface positioned at one end portion of the casing in the first direction. The electrical contact surface is positioned opposite the developing electrode in the second direction with respect to a part of the supply electrode.

A conveyance device includes a first temperature detector and a second temperature detector that detect a temperature of a heater. A recording medium detector detects a recording medium. The first temperature detector is separated from a center position of an elastic layer of a pressure rotator farther than the second temperature detector is in an orthogonal direction perpendicular to a recording medium conveyance direction. The first temperature detector is separated from the center position for a first length and disposed in a first span defined by the center position in the orthogonal direction. The recording medium detector is disposed in a second span opposite to the first span, separated from the center position for a second length smaller than the first length, and disposed in a minimum recording medium conveyance span where the recording medium having a minimum width in the orthogonal direction is conveyed.

An image forming apparatus includes a transfer unit forming a transfer nip portion, a fixing unit forming a fixing nip portion, and first and second belt suction conveyance units to suck a sheet onto a first belt and a second belt, respectively. The fixing nip portion is arranged at a position above the transfer nip portion. In a sheet conveyance direction, an upstream end portion of the first belt in the first belt suction conveyance unit is provided below the transfer nip portion, a downstream end portion of the first belt is provided above an upstream end portion of the second belt in the second belt suction conveyance unit, and a downstream end portion of the second belt is provided below the fixing nip portion. The first and second belts are inclined from a lower position to an upper position from upstream to downstream in the sheet conveyance direction.

An image forming apparatus includes a fixing device having a heater, a first temperature detection unit, a pair of second temperature detection units, a pair of first sheet-width detection units, a pair of second sheet-width detection units, and a control unit. The heater includes a first heat generating element, a second heat generating element having a length smaller than a length of the first heat generating element in a longitudinal direction, and a third heat generating element having a length smaller than the length of the second heat generating element in the longitudinal direction. The control unit controls a temperature of the heater based on a detection result of the pair of first sheet-width detection units, a detection result of the pair of second sheet-width detection units, and a detection result of the pair of second temperature detection units.

A flexible touch panel including a flexible substrate bent in a first direction, and a touch sensor unit disposed on the flexible substrate, the touch sensor unit including a bridge extending in a second direction intersecting the first direction.

A sheet conveyance apparatus includes a conveyance roller, a first rotary member forming a first nip portion conveying a sheet in a first conveyance direction, a rotation axis of the first rotary member being inclined with respect to a rotation axis of the conveyance roller such that a center of one end of the first rotary member is positioned at a different position in the first conveyance direction with respect to a center of the other end, and a second rotary member forming a second nip portion conveying a sheet in a second conveyance direction, a rotation axis of the second rotary member being inclined with respect to the rotation axis of the conveyance roller such that a center of one end of the second rotary member is positioned at a different position in the second conveyance direction with respect to a center of the other end.
