How do I remove an image from an image view? I want the image view to remain but to remain blank with a black background

Have you tried setting .image=None?

As @JonB wrote, None works. Try it ...

from ui import *


class MyView(View):
    def __init__(self):
        self.width = 320
        self.height = 320

        iv = ImageView()
        iv.background_color = '#ffff00'
        iv.width = 50
        iv.height = 50
        iv.center = self.center
        iv.image = Image('iob:folder_24')
        self.add_subview(iv)
        self.iv = iv

        b = Button()
        b.title = 'Remove Me'
        b.width = 100
        b.height = 44
        b.center = self.center
        b.y = self.bounds.y + 10
        b.action = self.remove_image
        self.add_subview(b)

    def remove_image(self, sender):
        self.iv.image = None

view = MyView()
view.present('sheet')

Thank you so much!!!!!!!
