摘要： A lens driving device is provided to reduce a number of required high-accuracy components and also eliminate the unevenness of maximum displacement of a lens holder with respect to a base. An outer edge of a lower spring plate is clamped by a lower casing served as a base and a lower spacer. A first protrusion is formed on a sidewall of the lens holder and protruding outward therefrom. A second protrusion protruding toward the lens holder is formed on an inner circumference of the lower spacer and extends to a position above and separating from the first protrusion by a distance S. The first protrusion props against the second protrusion when the lens holder is moved toward an imaged-object side and reaching a displacement of the distance S.

摘要： A toner for developing an electrostatic image is formed of toner particles; wherein each toner particle includes (i) 100 wt. parts of a binder resin having a glass transition point (Tg) of 50-70° C., (ii) 0.2-20 wt. parts of solid wax, and (iii) colorant particles or magnetic powder, (iv) lubricant particles carrying a liquid lubricant, so that the toner particle retains at its surface the liquid lubricant gradually released from the particles (iv). The toner may be further blended with an organically treated inorganic fine powder to provide a developer. The toner or developer retains good lubricity and releasability so that it is suitable to be used in an image forming method including means contacting a latent image-bearing means, such as a contact charging means, a contact transfer means or a contact cleaning means.

摘要： A cleaning device includes first to third cleaning members that clean a surface of an endless belt that is looped over rollers including a driving roller. The first cleaning member is brought into contact with and separated from the surface at a predetermined timing. The second cleaning member is disposed upstream of the first cleaning member and downstream of the driving roller in a movement direction of the endless belt. The second cleaning member is in contact with the endless belt so as to prevent a tension variation of the endless belt caused by the first cleaning member from affecting the driving roller. The third cleaning member is disposed downstream of the first cleaning member. A contact state in which the third cleaning member is in contact with the endless belt is switched from a first contact state to a second contact state so as to reduce the tension variation.
