A fastening structure which fixes a doctor blade to a holder is provided, which includes a cylindrical portion provided on one surface of the holder with which a doctor blade is overlapped, a through hole having an inner diameter larger than an outer diameter of the cylindrical portion and penetrating through the doctor blade. In the fastening structure, while the cylindrical portion is inserted through the through hole with a gap between an outer circumference of the cylindrical portion and an inner circumference of the through hole, an end portion of the cylindrical portion is pressed to be expanded in an outer circumferential direction and then bent towards the doctor blade, to thereby fix the doctor blade to the holder by supporting it between the end portion and the one surface of the holder.

Fastening structure, blade structure, develop unit, and image formation apparatus

A fixing device () including a fixing member (), a pressure member () forcibly contacting with the fixing member, and a separating plate () for separating a transfer paper () ejected from a nipping part () formed by the fixing member and the pressure member contacting with the fixing member, from the fixing member, the separating plate including an edge part () disposed close to the fixing member, the separating plate being disposed relative to the fixing member so that a sum of a thickness of the edge part of the separating plate and a gap () formed between the edge part and the fixing member is lesser than a minimum lift height of the transfer paper ejected from the nipping part.

Separating plate, fixing device having the separating plate with an edge part that abuts with the fixing member, method for producing the separating plate and image forming apparatus

A method for attaching a part, including preparing an optical part-holding member for holding an optical part and a housing member having a bottom wall and mountable the optical part-holding member, identifying a plurality of part-attaching portions forming nodal points on the bottom wall of the housing member, and fixing the optical part-holding member for holding the optical part to the part-attaching portions by spacing from the bottom wall of the housing other than the part-attaching portions.
