摘要： An image forming apparatus incudes an outer casing, a button portion including a pressed portion, a support portion and a deformable portion, and a regulation portion configured to come into contact with the support portion to regulate a position of the button portion. The button portion is movable from a first positon to a second position when the pressed portion is pressed. When the button portion is moved from the first position to the second position, the outer casing of the image forming apparatus slides with the button portion and a force is applied in a second direction orthogonal to a first direction to cause the deformable portion of the support portion to deform and the button portion to move in the second direction.

摘要： An image forming apparatus includes a cartridge including a portion-to-be-positioned, and an apparatus main body on which the cartridge is mounted in a mounting direction. The apparatus main body includes a positioning portion and a regulating portion. The positioning portion positions the cartridge by engaging with the portion-to-be-positioned. The regulating portion is provided on an upstream side of the positioning portion in the mounting direction. The cartridge includes a portion-to-be-regulated provided on an upstream side of the portion-to-be-positioned in the mounting direction. The portion-to-be-positioned engages with the regulating portion before engaging with the positioning portion, to regulate movement of the cartridge in the direction orthogonal to the mounting direction. The portion-to-be-regulated engages with the regulating portion before the portion-to-be-positioned engages with the positioning portion, to regulate movement of the cartridge in the direction orthogonal to the mounting direction.

摘要： A destaticizing brush includes a grounding member, a conductive brush member, and an adhesive tape member. The conductive brush member is bent back in a U-turn shape along an outer periphery of the grounding member in a direction in which a longitudinal direction intersects the grounding member such that the conductive brush member is in electric contact with the grounding member. An outer periphery of the conductive brush member that has been bent back and the grounding member are adhered in an integrated manner with the adhesive tape member, and at least one end of the conductive brush member is exposed from the adhesive tape member.

摘要： An image forming apparatus for forming an image on a recording material includes a mounting portion to which a cartridge is detachably mounted and a drive transmission member for transmitting a driving force by being engaged with a drive-transmitted member provided on the cartridge when the cartridge is mounted to the mounting portion. In addition, a protecting member is movable between a protecting position where the drive transmission member is prevented from being exposed toward the mounting portion and an open position where the protecting member is retracted from the protecting position to expose the drive transmission member to the mounting portion thereby to permit engagement of the drive transmission member with the drive-transmitted member.

摘要： An image forming apparatus includes an image forming unit, a discharge unit, a double-sided conveyance path, a sheet plate, a skew correction unit, and a frame. The discharge unit discharges a sheet having an image from the image forming unit. The double-sided conveyance path conveys the sheet again to the image forming unit. The sheet plate restricts a position of an end, in a sheet width direction, of the sheet. The skew correction unit obliquely conveys the sheet to abut the sheet end. The frame determines a position of the sheet plate and includes a first positioning portion to position a sheet plate first positioned portion and a second positioning portion to position a sheet plate second positioned portion with the skew correction unit between the first and second positioned portion. The first positioning portion faces the first positioned portion and the second positioning portion faces the second positioned portion.
