摘要： Measures for controlling an engagement force between a photo imaging plate (110) and a developer roller (200) in a printing device (100) are described. A motor (310) is operated to generate rotational motion. The rotational motion is translated into linear motion. The linear motion causes an adjustment to the engagement force between the developer roller and the photo imaging plate. A characteristic of the motor is monitored. The motor is controlled on the basis of the monitored characteristic in order to maintain a desired engagement force between the developer roller and the photo imaging plate.

摘要： An image forming apparatus includes an image carrier that carries a latent image, a developer holder that holds developer for developing the latent image carried by the image carrier, and a layer-thickness restriction member that restricts the layer thickness of the developer held by the developer holder. When the developer holder approaches the layer-thickness restriction member, the layer-thickness restriction member moves away from the developer holder and then toward the developer holder.

摘要： A developing device includes a developer bearing member. A lubricant is applied to a surface of the developer bearing member. In an axial direction of the developer bearing member, an end of the developer bearing member is located further outward than an outer end of a seal member, and an end of a cleaning member is located further outward than the end of the developer bearing member. In the axial direction of the developer bearing member, a first application quantity of the lubricant applied to the surface of the developer bearing member at a position further outward than the outer end of the seal member is larger than a second application quantity of the lubricant applied to the surface of the developer bearing member at a position corresponding to an opening.
