摘要： A process cartridge includes an image bearer, a developer bearer, and a positioning member. The image bearer is rotatable. The developer bearer is rotatable and opposite to the image bearer. The positioning member determines an opposing distance between the image bearer and the developer bearer, and includes a fitting portion and a groove. A fitted portion of the image bearer rotatably fits to the fitting portion. The groove extends from a ceiling portion to a bottom portion. A shaft portion of the developer bearer is slidingly movable in the groove. The groove is formed such that the shaft portion of the developer bearer contacts the bottom portion and is supported by the bottom portion. The ceiling portion of the groove is open upward so that the shaft portion of the developer bearer is insertable to and removable from the groove.

摘要： A lubricant application apparatus including a lubricant application member and an elastic member. The lubricant application member applies lubricant to a lubricant receiving member moving in a given surface movement direction. The elastic member contacts the lubricant receiving member in a counter direction with respect to the surface movement direction of the lubricant receiving member, and smoothes the lubricant applied on the lubricant receiving member. The elastic member is in contact with the lubricant receiving member at a contact area of the elastic member, in the counter direction. The elastic member is positioned in a downstream side of the surface movement direction of the lubricant receiving member with respect to the contact area of the elastic member. The elastic member is in contact with the lubricant receiving member at the contact area with a contact angle of 85 degrees or more.

摘要： A tandem-type electrophotographic image forming apparatus includes multiple color image forming units using a dry toner, a first black image forming unit using the dry toner, and a second black image forming unit using a wet toner and performs an image formation with the dry toner in a first printing mode and an image formation with the wet toner in a second printing mode. The image formed in the second printing mode with the wet toner is fixed to a recording medium at a temperature lower than the image formed in the first printing mode with the dry toner. Each of the image forming units corresponds to a process cartridge that is removably installable in the tandem-type electrophotographic image forming apparatus and including an image carrier and other image forming components integrally therein.

摘要： A switching transistor has a source connected to the ground and a drain connected to the first terminal. The other end of an inductor whose one end is to be connected to the first terminal is connected to the second terminal. An input voltage is applied to the third terminal. An auxiliary transistor is disposed between the second terminal and the third terminal. A first soft start circuit generates a first soft start voltage that increases with lapse of time, and a second soft start circuit generates a second soft start voltage that increases with a delay to the first soft start voltage. An error amplifier controls the gate voltage of the auxiliary transistor on the basis of the error voltage between the output voltage and the first soft start voltage.
