A protruding portion protruding in a rotation axis direction of an image bearing member is provided at a position between the tip of a separation claw and an apex of the separation claw, when the apex of the separation claw is disposed at a position farthest from the surface of the image bearing member in a direction perpendicular to a straight line connecting the tip and the rotation center of a shaft portion of the separation claw.

An image forming apparatus includes an apparatus body, an image bearer, and a rotator opposed to the image bearer. The rotator is removably installable in the apparatus body. The image forming apparatus further includes a guide configured to guide the rotator in a longitudinal axial direction of the rotator toward a regular position where the rotator is installed in the apparatus body.

A sheet conveying device includes a control unit. The control unit determines whether a first sheet and a second sheet being double-fed are in a full double feed state in which the first sheet and the second sheet are conveyed while overlapping each other from distal end parts of the first sheet and the second sheet in a conveyance direction or a partial double feed state in which the second sheet is conveyed while overlapping a rear part of the first sheet than the distal end part of the first sheet, stops an operation of a sheet conveying mechanism when it is determined that the sheets are in the full double feed state, and performs double feed elimination control for eliminating the double feeding of the sheets without stopping the sheet conveying mechanism when it is determined that the sheets are in the partial double feed state.

An image forming apparatus includes an image carrier, a first peel-off unit whose end portion is in contact with the image carrier and that peels off a recording medium from the image carrier, and a second peel-off unit whose end portion is not in contact with the image carrier and that peels off a recording medium from the image carrier. The second peel-off unit is disposed in such a way that the end portion thereof is located at a position that is the same as or upstream of a position of the end portion of the first peel-off unit in a rotation direction of the image carrier, and the second peel-off unit is movable so that the end portion thereof moves away from the image carrier.

An image forming apparatus provided with a transfer device includes a separator, a post-transfer-residual-quantity acquirer, and a controller. The transfer device transfers an image formed on an image carrier to a transfer medium. The separator is arranged at downstream side from a transfer device in a conveying direction, is provided with a separation claw which contacts with the image carrier and separates the transfer medium from the image carrier, and performs contact/separate operation of the separation claw with/from the image carrier. The post-transfer-residual-quantity acquirer acquires post-transfer residual quantity in a region determined on a basis of a position of the separation claw in an axial direction of the image carrier. The controller controls the contact/separate operation of the separation claw with/from the image carrier on a basis of the post-transfer residual quantity acquired by the post-transfer-residual-quantity acquirer.

A separation member that is used to separate a conveyance object from two rotation members, the conveyance object having been sent out from a nip that is formed by the two rotation members that are in contact with one another, the separation member includes a wavy part directed toward the nip and inclined from a normal to a center line of the two rotation members at a predetermined angle. The wavy part covers a contact zone where the conveyance object can come into contact with the separation member along a conveyance direction and along a width direction of the conveyance object, and the wavy part has a plurality of depressions parallel to each other and extending in a direction inclined from the conveyance direction and inclined from the width direction, at least two of the depressions overlapping along the conveyance direction.

Peeling member formed by a metal plate having a resin coating film thereon, the peeling member being capable of preventing adhesion of a paper right after fixing for a long period of time, and to provide a manufacturing method for the peeling member capable of forming a fine recessed portion on a surface of the resin coating film for preventing the adhesion of the paper. Peeling member 1 includes a peeling sheet 1a having a base material 2 having a plate shape, and a resin coating film 4 formed on at least a surface of the base material 2 at a paper passing side. The peeling member is formed to peel a paper from a fixing member of an electronic photographic device by arranging a distal end portion 1c to be contacted with or close to the fixing member.

A fuser apparatus includes first and second rollers in nip relation to transport a receiver member therebetween. A stripping mechanism a skive assembly having an elongated, thin, flexible skive finger, wherein a tip of the skive finger is beveled forming a sharp edge along an upper surface of the skive finger. At least one raised bump protrudes from the lower surface of the skive finger, spaced apart from a tip of the skive finger. A mounting mechanism positions the skive finger in operative relation to the first roller with the at least one raised bump contacting the surface of the first roller at a contact point such that the sharp edge along the first surface of the skive finger is spaced apart from the surface of the first roller by a distance of between 50 and 120 microns.

A sheet-member separation device includes a first air blower, an attractor, a conveyor, a second air blower, and an adjuster. The first air blower blows air onto a front side of a stack of sheet members in a sheet-member conveyance direction. The attractor attracts an uppermost sheet member floated from the stack of sheet members by the air blown from the first air blower. The conveyor conveys, in the sheet-member conveyance direction, the sheet member attracted by the attractor. The second air blower blows air toward a lateral side of the sheet member. The adjuster moves the second air blower and the attractor together to adjust positions of the second air blower and the attractor in the sheet-member conveyance direction.

A recording medium processing device includes: a pair of contacting members including a first contacting member and a second contacting member, the first contacting member and the second contacting member contacting each other at a contact portion and contacting a recording medium passing through the contact portion, a contact position of the second contacting member on the first contacting member changing in response to displacement of the second contacting member with respect to the first contacting member in a state of being held in a position for recording medium transportation; and a guide member mounted to the second contacting member, the guide member guiding the recording medium having passed through the contact portion at which the first contacting member and the second contacting member contact each other.
