摘要： When a mechanism enters a first state, an intermediate transfer member separates from a second photosensitive member. When the mechanism enters a second state, the intermediate transfer member contacts the second photosensitive member. When a first monochrome image is formed on a sheet of a first type by using toner of a first color, the mechanism enters the first state. When a second monochrome image is formed on a sheet of a second type by using toner of the first color, the mechanism enters the second state. A rotation speed of the second photosensitive member for forming the second monochrome image on the sheet of the second type is controlled to a predetermined rotation speed. The predetermined rotation speed is slower than a rotation speed of the second photosensitive member for forming the second image.

摘要： An image forming apparatus includes a cartridge including a photosensitive drum; an endless belt configured to transfer the toner image formed on the drum; an endless belt supporting member movable between a contacting position for contacting the belt to the drum and a non-contacting position retracted from the contacting position away from the drum; and a cartridge supporting member movable between an image forming position in which the drum contacts the belt taking the contacting position and a non-image-forming position in which the cartridge is movable from a inside to a outside of the main assembly. By movement of the belt from the contacting position to the non-contacting position, a space capable of accommodating at least a part of the cartridge supporting member taking the non-image-forming position and/or the cartridge supported by the cartridge supporting member taking the non-image-forming position is provided.

摘要： An image forming apparatus includes an image forming section, a transferring member, and a controller. The image forming section includes an image supporting member and a developer supporting member. The image supporting member supports a latent image on a surface of the image supporting member. The developer supporting member supports, on a surface of developer supporting member, a developer that develops the latent image. The transferring member transfers, onto a transferred medium as a medium on which a transfer is to be performed, an image formed by the image forming section. The controller controls, as an amount of the developer, a developer amount to be fed to the latent image supported on the surface of the image supporting member, on the basis of a traveling velocity of the transferred medium.

摘要： An image forming device (1) has an image carrier (331), a transfer member (35), a holding member (81) which holds the transfer member, a pressing member (83) which changes a position between a first position and a second position to make the transfer member contact and separate from the image carrier, a first moving member (325) and a second moving member (10P1) which are movable, and a first interlocking mechanism (33T) and a second interlocking mechanism (10Q). The first interlocking mechanism and the second interlocking mechanism press the pressing member to change a position of the pressing member in conjunction with the first moving member and the second moving member. The pressing member includes a first pressed portion (83P1) which is pressed by the first interlocking mechanism, and a second pressed portion (83P2) which is pressed by the second interlocking mechanism.

摘要： An image forming apparatus includes a first image bearing member, a second image bearing member, an intermediate transfer belt, a first primary transfer member, a second primary transfer member, a secondary transfer outer member, a pre-secondary transfer stretch roller, a driving roller, and an execution portion. The execution portion is configured to execute a first monochromatic mode in which a bias smaller than the primary transfer bias applied to the first primary transfer member in a case where a toner image is formed on the first image bearing member is applied to the first primary transfer member, and the primary transfer bias applied to the second primary transfer member in a case where a toner image is formed on the second image bearing member is applied to the second primary transfer member.

摘要： In one embodiment, an image forming apparatus has an image carrier, a transfer unit, and a spacer. The image carrier has a toner image carrying surface. The transfer unit transfers a toner image from the toner image carrying surface to a recording medium. The transfer unit includes a transfer roller which forms a nip with the image carrying surface and a contact roller provided coaxially with the transfer roller. The spacer is detachably provided on the transfer unit to separate the image carrier and the transfer unit. The transfer roller forms the nip with the toner image carrying surface when the spacer is detached from the transfer unit.

摘要： A positional relationship between a photosensitive drum and an intermediate transfer belt during a period from the start of the driving of the photosensitive drum to the start of image formation, or during a period of the end of the image formation to the stop of the driving of the photosensitive drum enters a separating state in a case where the image formation is executed when the process speed is a first speed, and enters a contacting state in a case where the image formation is executed when the process speed is a second speed.

摘要： A spacing device includes a spacing member that spaces first and second rotating bodies having first and second shaft portions, respectively, apart from each other. The spacing member is provided on the second shaft portion and includes a supporting portion that supports the first rotating body; and an opening through which the second shaft portion extends and including an idling portion that allows a hook part of the second shaft portion to rotate idle, and a catching portion that catches the hook part. The first and second rotating bodies are spaced apart when the hook part is in the catching portion and the first rotating body is supported by the supporting portion. The first and second rotating bodies are allowed to rotate when the spacing member rotates until the supporting portion is oriented downward in a direction of gravitational force and the hook part moves to the idling portion.
