摘要： An image forming apparatus includes a main casing and a cartridge detachably mountable therein. The cartridge includes a photosensitive drum and a developing roller disposed to oppose each other. The main casing includes: a metal frame for supporting the cartridge; a lock member supported to the metal frame and movable about a first axis to allow or restrict movement of the photosensitive drum relative to the metal frame; and a contact-separation member supported to the metal frame and movable about a second axis to allow contact and separation of the developing roller relative to the photosensitive drum. The lock member and the contact-separation member are aligned in an orthogonal direction orthogonal to an axis of the photosensitive drum such that the first axis is not overlapped with the contact-separation member or the second axis is not overlapped with the lock member in an axial direction of the photosensitive drum.

摘要： A transfer belt has a two-layer structure consisting of two inner belts formed of metal, such as stainless steel, and an outer belt formed of an elastic material, such as silicone rubber, being spread across the inner belts. The inner belts are endless and wound around transfer rollers, while the outer belt has its ends which are not joined with each other and form an opening therebetween. Distortion of the outer belt due to stress is designed to be suppressed by using a reinforcing member around the opening.

摘要： A print head cap includes a bottom surface; and a ring-like lip. The ring-like lip surrounds the bottom surface, protrudes toward a nozzle surface of a print head of an ink jet printer and is elastically deformable. The ring-like lip is pressed onto the nozzle surface to cover the nozzle surface therewith. The ring-like lip has corners that change the direction surrounding the bottom surface. The corners of the ring-like lip are more elastically deformable than the other portions of the ring-like lip.

摘要： An ink-jet recording apparatus has rollers, a conveyor belt, a conveyor belt driving mechanism, an ink-jet head, an absorber, a scraper, a supplier, and a supply controller. The conveyor belt spans the rollers. The driving mechanism rotates the rollers to move a record medium disposed on one surface of the conveyor belt in a predetermined conveyance direction. The absorber absorbs cleaning fluid and contacts and applies the cleaning fluid to the one surface of the conveyor belt. The scraper comes into contact with the one surface of the conveyor belt and scrapes the cleaning fluid attached to the one surface. The supplier supplies cleaning fluid to the absorber. The supply controller controls a supply of cleaning fluid from the supplier to the absorber, so that the supply controller makes the supplier supply cleaning fluid to the absorber in response to a print command, for a first period of time before the driving mechanism rotates the rollers to make the conveyor belt start traveling.
