    摘要: A method for manufacturing a galvanized steel sheet, includes: galvanizing a steel sheet; bringing the surface of the steel sheet into contact with an aqueous solution containing zinc ion in the range of 5 to 100 g/l as the zinc ion concentration, having a pH of 4 to 6, and having a liquid temperature of 20 to 70° C., holding the steel sheet for 1 to 60 seconds; and then washing and drying the steel sheet. The solution containing zinc is preferably one containing zinc sulfate, for example. According to the method, a galvanized steel sheet having an oxide layer having an average thickness of 10 nm or more and mainly containing zinc formed on the surface of the steel sheet and having excellent press formability can be stably manufactured in a short time.

    摘要: A sheet feed device includes a sheet tray and a guide unit. The sheet tray is configured to store a recording medium including a recording sheet. The guide unit is configured to support detachably the sheet tray. The guide unit includes a rotary member that is configured to contact an outer bottom surface of the sheet tray while contacting an outer side surface of the sheet tray, and rotate with mounting and detachment of the sheet tray. An image forming apparatus includes an image bearing member for bearing a latent image on a surface thereof, an exposure unit for exposing the image bearing member to form the latent image, a developing unit for developing the latent image with toner to form a visible image, a transfer unit for transferring the visible image onto the recording medium, and the sheet feed device.
