摘要： An image forming apparatus includes a primary transfer unit 42 that is attachable and detachable. The primary transfer unit includes a contact and separation mechanism 62 that causes primary transfer rollers 60 to come into contact with and separate from photoreceptor drums 36. The contact and separation mechanism includes a plurality of arm members 76, a link member 78, a cam member 80, and a first grip 92. In the contact and separation mechanism, the cam member rotates by receiving a driving force from a drive source to cause the link member to reciprocate to a color position and a monochrome position, and the link member is moved to a release position by a user by using the first grip to cause all of the primary transfer rollers to separate from the photoreceptor drums.

摘要： An image forming apparatus includes a transfer unit that comes into contact with a target object and that transfers an image to the target object, a holding portion that holds the target object including a circumferential surface such that the circumferential surface rotates along a transfer direction of the transfer unit, and a transport unit that transports the target object held by the holding portion along a transport route, that stops transportation of the target object in a case where the transfer unit transfers the image to the target object, and that causes the target object to be separated from the transfer unit before a surface of the target object on which transfer of the image is finished comes into contact with the transfer unit again.

摘要： An image-forming apparatus includes first and second photosensitive drums, first and second image-forming portion including first and second development rollers configured to bear developers composed of first and second toner particles and organosilicon protrusions formed on surfaces of the first and second toner particles, an intermediate transfer member to which a developer image is to be transferred in first and second contact portions in contact with the first and second photosensitive drums, and a transfer member configured to transfer the developer image to a recording material in a transfer portion. The first contact portion is formed downstream of the transfer portion and upstream of the second contact portion in a movement direction of the surface of the intermediate transfer member. A protrusion formed on the second developer has a lower height than a protrusion formed on the first developer.

摘要： Plural write control units independently control plural print mechanisms corresponding to plural toner colors. A controller stores a setting value for each page into a first memory area. Plural second memory areas respectively correspond to the plural write control units. Further, one write control unit among them transfers the setting value from the first memory area to the second memory area of this write control unit, and applies the setting value stored in the second memory area and causes the corresponding print mechanism to print a page image. Another write control unit among them transfers the setting value to the second memory area of this write control unit from the second memory area of another write control unit among them, and applies the setting value stored in the second memory area and causes the corresponding print mechanism to print a page image.

摘要： An image forming apparatus comprising a transfer means for transferring, a developer image onto a recording material; a discharging unit for discharging the recording material; a first circuit that applies a first voltage of reverse polarity to the developer to the transfer unit; a second circuit that applies a second voltage of identical polarity to the developer to the transfer unit and the discharging unit; and a control unit. The control unit applies a transfer voltage which is a superposition of the first and the second voltage to the transfer unit, and applies a discharging voltage which is a partial voltage from the second voltage. When the discharging voltage is set to the first value, the control unit reduces the discharging voltage in a case where the transfer voltage is lower than a target value.
